Touch Proof Terminations

Raychem RPG’s ELBC screened separable connectors are designed to connect single and three-core polymeric cables to medium-voltage gas insulated switchgear and other equipment using CENELEC bushings Type C1=630 A and C2=1250 A, specified up to 33 kV.
Made up of a highly modified insulating material and protected by a thick walled outer conductive screen connected to earth, ELBC connectors are equally suited for both indoor and outdoor installations.
Supporting a wide application range, the design incorporates one body and two stress cone adapters to cover all cross-sections from 35 to 800 mm 2 . The overall and cut back dimensions are designed to take up minimum space in the terminal box.

Features:

• 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.

Ideal Applications:

• 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 RSTI Touch Proof Terminations are designed to connect single- and three-core polymeric cables to medium-voltage gas insulated switchgear and other equipment using CENELEC bushings Type C 1 =630 A and C 2 =1250 A, specified up to 42 kV. Made of a highly modified silicone rubber and protected by a thin walled outer conductive screen connected to earth, RSTI connectors are equally suited for indoor and outdoor installation.
Supporting a wide application range, the design incorporates one body and two stress cone adapters to cover all cross-sections from 35 to 300 mm2. The overall and cut back dimensions are designed to take up minimum space in the terminal box. RSTI connectors are equipped with a capacitive test point for determining whether the circuit is energised. A conductive cap protects this test point.

Features:

• The insulation of the connector is made of a highly modified silicone rubber characterised by high tracking resistance, elongation at break and non-flammability.
• A thin 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.
• The screened cable connector exceeds CENELEC HD 629.1 S2 requirements, which includes BS; VDE and other international specifications.
• Design fits 630 A and 1250 A bushings (Interface “C 1 ” and “C 2 ”) 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 300 mm2.
• Conductor connection with mechanical, DIN or deep indentlugs.
• Easily accessible rear plug with capacitive test point.
• Few accessories required for system test, double “T” and earth connection.
• Complete kit including lugs facilitates installation and storage.

Design And Construction:

• Screened body: A thin walled conductive outer screen is permanently bonded to the silicone rubber insulating material of the body.
• Inner screen: A conductive inner layer, as a Faraday cage around the compression or mechanical lug, prevents corona at rated voltage.
• Compression or mechanical lugs: Specially designed DIN and deep indent compression lugs, as well as tinned, mechanical lugs with shear bolts for connecting either aluminium or copper conductor cables.
• Stress cone adapter: Relieves electrical stress at the point where the cable screen is cut. The insulated section, extending beyond the wire shielding, provides a convenient point for over sheath testing.
• Earthing eye and ground lead: Provides a connection point for earthing the screen.
• Threaded pin: A threaded pin together with a spring washer (wave type) and hex nut ensure a high performance electrical and mechanical contact with the bushing.
• Rear plug with test point: Removable rear plug with capacitive test point.
• Test point: The test point is used to determine whether the circuit is energised; alternatively it can be used for phasing.
• Conductive end cap: Electrical screen and protection of the rear end of the separable connector.

Raychem Screened Gapless Surge Arrester is a “T“-shaped product. It is designed for direct connection onto outer cone bushings in accordance to EN50180 or EN50181 with interface type “C” or for parallel connection mating to the rear entry of the base screened connector system RSTI designed for system voltage up to 41 kV.
The insulation of the screened surge arrester is made of a highly modified silicone rubber characterised by high tracking resistance, elongation at break and non-flammability.
A thin walled screen is permanently bonded onto the insulation and protects the connection system against unintentional contact.
The active part is a metal oxide arrester which meets the requirements of IEC-60099-4 for separable and dead-front arresters.
The combination of screened connector and surge arrester exceeds CENELEC HD 629.1 S2 requirements, which includes BS, VDE and other international specifications.
Easily accessible rear plug with capacitive test point. Few accessories required for system test and earth connection. Complete kit including screened surge arrester, threaded pin and ground lead for three phases facilitates installation and storage.
