Raychem Heat Shrink Straight Through Joints: The design of a single-core joint for a polymeric insulated cable is described here. The same design principles are used for 3-core cables. For transition joints, special oil barrier tubing are used to transform a draining oil (MI) as well as non draining oil (MIND) paper insulated cable into a quasi polymeric insulated cable with a radial field.

• Electrical stress control: The stress control tubing and the patch have a precisely defined impedance characteristic which smoothes the electrical field over the connector and cable screen ends. During the installation of 12 kV and 24 kV joints, the special void filling yellow tape will be compressed by the two stress control tubing. The patch over the connector will be compressed by the high shrink force of the triple extruded joint body. For the design of a 42 kV joint only the special yellow void filling tape is used, which is compressed by one stress control tubing. It is not necessary to chamber the cable insulation or to use a connector with specially profiled shape.
• Insulation and screen: The triple extruded joint body provides the correct thickness of insulation (red) in one installation step. The insulation screen is provided by the outer wall of the tubing, which is of heat-shrinkable conductive polymer (black). This technique saves installation time and ensures a flawless bond between joint insulation and screen, even up to 42 kV.
• Metallic shielding: Copper mesh and roll springs ensure the correct screen connection across the joint area and make electrical contact with the outer screen of the joint. The design passed tests up to 11 kA short circuit and up to 400 A currents simulating ground fault situation.
• Outer sealing and protection: The heat used to shrink the outer tubing causes the pre-coated adhesive to melt and flow, resulting in a lasting moisture and corrosion barrier on the cable oversheath. The outer tubing provides mechanical impact and chemical resistance as expected from cable oversheaths. For armoured cables, Raychem joints incorporate either a quick to install galvanised steel joint case or steel tape or fibre glass reinforced heat-shrink wraparound.

Installation Procedure
The elastomeric joint component and the outer sealing tubing are slid over the prepared cable end. The screen ends are electrically smoothed with void filling compound and stress control tubing are shrunk over the cable ends. By simply tightening the bolts of the mechanical connector, the conductors are jointed and then covered with a stress control patch. The elastomeric component is quickly shrunk over the connection area. Roll springs and copper mesh rebuild the cable shield and the oversheath is replaced by an adhesive coated sealing tubing. All kits are supplied with illustrated step by step instructions.

Triple Extruded Elastomeric Technology
The triple extruded joint body, supplied in an expanded form, consists of 3 bonded layers. The two heat-shrinkable outer layers (1. black conductive, 2. red insulating) hold the inner elastomeric layer (3. red insulating) at full diameter. Application of the heat causes the outer layers to shrink, allowing the elastomeric, insulating layer to contract at the same time and closely fit on the jointing cable. Elastomers typically experience a reduction of the contraction force after storage and at cold temperatures. By applying heat this effect is overcome thus allowing an unlimited storage time and installations at low temperatures. The rubber-like characteristics of the insulation material combined with the rigid outer heat-shrinkable wall enable the joint to follow the thermally induced dimensional changes of the cable insulation.

While several advances have recently been made in the materials and designs of medium voltage accessories, the techniques for jointing and terminating low voltage cables have largely remained unchanged. Traditionally these have relied upon casting the jointed cables placed inside a slim, compact two part plastic mould with a casting resin typically polyurethane. The purpose of providing a slim, compact mould was to minimise the use of the casting resin which constituted the main price component. The slim mould made the accommodation of the joint with proper clearance between the cores and mould difficult if not impossible especially because of the curvature of the cable ends unwound from drums. Mixing and pouring of the resin, leakage through mould flanges and poorly sealed cable entry ends makes the installation craft sensitive and cumbersome. The resins have limited shelf life and cannot be stocked for emergency use in unpredictable cable breakdowns. The polyurethane resins are not effective in the presence of moisture and are hazardous to health.
Raychem RPG, a pioneer in heat shrinkable cable accessories and the largest manufacturer of cable accessories in India now offer an ideal cable jointing system in the form of ‘RLVJ’ kits. RLVJ joints have been developed keeping in mind the customers requirements of reliability, safety, cost and convenience. RLVJ kits rely on the insulating and sealing properties of a unique mastic coated polymer tape ‘Polystix’ that forms a tough tenacious water tight seal on the cable insulation and femule while providing a high level of factory engineered insulation. Polystix can be easily and effectively applied by any electrician/jointer.. The only effort is the removal of the backing from the mastic and application over the connectors. An elastomeric core separator and mastic enhance the insulation and sealing system of the joint. RLVJ joints have a realiable electrical continuity of the armour through a tinned copper braid and are fully shielded with a steel mesh which in combination with a tough, radiation cross linked heat shrinkable sleeve having a hot melt adhesive coating on its inner surface, provides mechanical protection, sealing and corrosion protection. The kits have unlimited shelf life and can be safely stocked for emergency use. Free installation training is provided to enable the simplest craftsman to reliably, easily and quickly install RLVJ joints.
The performance of RLVJ kits on both PVC cables and XLPE cables has been successfully evaluated at CPRI, Bangalore in accordance with the UK Engg. Recommendations C-81. Several lending utilities like BSES, BEST, NDMC etc have successfully introduced RLVJ kits in their system.

The increasing popularity of gas insulated switchgear called for the development of appropriate connection systems to standardised bushings in accordance to EN50181.
Tyco Electronics Energy Division has developed two systems, one is related to the outer cone and the other one to the inner cone system. Later is used in power switch gear and power transformers.
Tyco Electronics Energy Division has several decades of experience in the field of hermetically insulated termination systems for medium voltage applications. Thus the bushings designed for gas insulated switchgear meet the standard EN50181 for connection type size 2 (800 A) and size 3 (1250 A) at operating voltage 12 kV up to 36 (42) kV.
The basic construction of the mating termination follows well known design principles and incorporates a lamellate contact system which ensures reliable current transmission via a cone clamp to the conductor. The interface between silicone body of the termination and the bushing is kept permanently sealed via the pressure of a spring between the insulator and the flange of the termination cover. The termination cover is sealed at the flange area with well known sealing methods and at the cable side with heat-shrinkable tubing against ingress of moisture.

Features:

• Separable inline connection for high current, gas insulated switchgears up to 42 kV.
• Termination mates interfaces in accordance to EN50180 and EN50181 for inner cone connections.
• The contact parts are designed for stranded circular aluminium or copper conductors in accordance to IEC-60228.

Transtormer is a vital component of a distribution system. It has to deliver Reliable Power in a safe & efficient manner. However, 8% of the transformers installed worldwide fail on account of improper connector systems.  

A conventional connector system used for LV cable connection, deploys crimping and tightening of the bolts. Over a period of time, it leads to a loose electrical contacts which causes sparks and hot spots. The contact resistance is high which adds to the losses of ailing utilities. The weight of the connector causes mechanical strains on the bushing of the transformer, leading to oil leakages. 

Raychem Trafo Connector engineered to keep the contact resistance low for the lifetime of the transformer. Its lighter & pretty simple to install as it uses the modern shear bolt technology. hence avoiding the skill & tool dependent crimping methodology. It significantly increases the reliability of the transformer.

• Low I'R (Technical) losses
• No crimping & hence no tools required
• Light weight
• Reliable, insulated & safe connection
• Simple & easy installation
• No chances of Ph-Ph, Ph-N & Ph-E faults

The Surge Arrester monitoring instruments are fully tested for use with any manufacturers surge arrester. The SC003 is a Surge Counter & also provides the additional measurement of total leakage current. The analogue instrument provides a means of monitoring the current through the arrester and the leakage current over the surface of the arrester housing. Significant changes after installation may indicate a deterioration in the arrester or a buildup of surface contamination.
These instruments, which require no auxiliary supply, are designed for installation in the earth connections of a single surge arrester or alternatively the SC003 may be used with the common earth of a three phase set. Fully weatherproofed and sealed for life they are housed in a one piece gravity die cast aluminum case coated to enhance its already high degree of resistance to surface corrosion. The glass viewing window is sealed in place, using a silicon rubber adhesive, and a desiccator is enclosed to ensure any residual moisture trapped during sealing is absorbed for the service life of the counter. Mounting is effected by means of an integrally cast lug at the rear of the case providing a single clearance hole for the galvanized steel M12 bolt supplied. The SC003 is service proven and require no special maintenance or servicing apart from general cleaning of the glass viewing window and the moulded epoxy resin line terminal bushing.

The Universal Medium Voltage Termination System for Polymeric and Paper Insulated Cables
Over the last three decades, engineers in utilities and industry around the world have specified million’s of Raychem cable terminations at distribution voltages up to 36 kV. Raychem terminations have become identified with reliability because of their unparalleled long-term performance where it really counts– in the field. Today there are many changes influencing the distribution of power at medium voltages. For example, the transition to new types of polymeric cable, distribution at higher voltages, and the widespread usage of compact switchgear.
Anticipating these industry changes, we have continued to extend and improve the product range, based on the extensive experiece both in the field and at our outdoor test sites in polluted and desert environments. Now these developments are incorporated in a new generation of Raychem heat shrinkable cable terminations, that are even easier to select and install, without compromising the reliability of proven materials technology. The improved system is simple to use, because the basic termination components and installation steps are the same – even if your net- work operates with voltages of 7.2 to 36 kV; if you use 12 kV belted paper cable and 24 kV water-blocked single core polymeric cable; whether you make equipment connections in a cable box or in compact switchgear.

Raychem WRSM Wraparounds are a fast and permanent cable repair and sealing system. The repair sleeve is quickly fitted in place by means of its rail and channel closure. A moisture-proof, insulating and tight-fitting repair is then obtained in one step by heating, which makes the sleeve diameter shrink and the adhesive coating melt and flow into interstices. Because of its heat-shrink ability, each WRSM size will fit several different cable diameters. The adhesive exhibits excellent bonding and sealing characteristics to all materials commonly used in the various cable and sheath constructions, such as plastic, rubber, lead and aluminium. WRSM wraparounds are made of an abrasion and corrosion resistant semi- rigid material, and are one result of our extensive capability in materials technology.As the world’s leading maker of heat- shrinkable materials, we offer a wide range of tubing’s and moulded parts for any application where a tight, insulating or fluid resistant cover is required over uniform or irregularly shaped objects. These products are available in a wide range of formulations to meet the demands of the growing world of energy.
