• 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.

Trust Raychem’s globally recognized Cable Jointing Kits for unmatched reliability and durability. With innovative materials and user-friendly designs, these kits reduce downtime and ensure safe, secure power distribution—no matter the challenge.

• 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.

• The insulation of the connector is made of a highly modified insulating rubber characterized by high tracking resistance, elongation at break and non-flammability.
• A thick walled screen is permanently bonded onto the insulation and protects the connection system against accidental contact.
• The screened connector need not be removed for over sheath testing.
• Design fits 630 A and 1250 A plug-in bushings (Interface “C1” and “C2”) as specified by EN 50180 and EN 50181.
• The compact design supports the use of double “T” connections inside standard terminal boxes.
• The wide application range covers cable cross sections from 35 to 800 mm2.
• Conductor connection with mechanical lugs ensures perfect tightening unlike crimping.
• Easily accessible rear plug with capacitive test point.
• Few accessories required for system test, double “T” and earth connection.

• Switchgear connections- ELBC is a perfect solution for MV side connections to switchgear. It has been widely used for connecting SF6 and Vacuum circuit breakers up to 33 kV for indoor application.
• Transformer connections- Some of the utilities have found the benefits of using ELBC, as touch-proof, compact MV connection system, to their outdoor type Distribution Transformers. This helps improve reliability by reducing external flashovers and making the complete connection system safe.

Raychem High Voltage Busbar Insulation Tape is a heat-shrinkable, flexible insulating tape designed to provide superior electrical insulation and protection for high-voltage busbars. It offers excellent resistance to tracking, UV radiation, moisture, and chemicals. The tape shrinks uniformly when heated, conforming to complex shapes and ensuring a tight, reliable seal. Ideal for indoor and outdoor applications, it enhances safety and extends equipment life in switchgear and substation environments.
