Raychem Screened, Separable Connection System RSTI-68 800 A up to 42 kV

Raychem Screened, Separable Connection System RSTI-68, 800 A up to 42 kV

Raychem RSTI 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 42 kV.

Applications Single connection Material requested for 3 phases: 1 x RSTI-68xx (Kit) 25

183 110

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.

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 “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 300 mm2. • Conductor connection with mechanical, DIN or deep indent lugs. • 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.

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.

Before Starting Check to ensure that the kit you are going to use fits the cable. Refer to the kit label and the title of the installation instruction. Components or working steps may have been improved since you last installed this product. Carefully read and follow the steps in the installation instruction.

General Instructions Use a propane (preferred) or butane gas torch. Ensure the torch is always used in a well-ventilated environment. Adjust the torch to obtain a soft blue flame with a yellow tip. Pencil-like blue flames should be avoided. Keep the torch aimed in the shrink direction to preheat the material. Keep the flame moving continuously to avoid scorching the material. Clean and degrease all parts that will come into contact with adhesive. If a solvent is used follow the manufacturer's handling instructions. Tubing should be cut smoothly with a sharp knife leaving no jagged edges. Start shrinking the tubing at the position recommended in the instruction. Ensure that the tubing is shrunk smoothly all around before continuing along the cable. Tubing should be smooth and wrinkle free with inner components clearly defined.

Installation of Solderless Earth Connection on 3-Core Cables Remove the oversheath of the cable according to the dimensions given in the appropriate Raychem Terminations Installation Instruction. Position the end of the earth lead on the metal tape shield of one core about 100 mm from the end of the oversheath. Starting at the opposite side of the core, wrap the roll spring twice over the earth lead, in the direction of the metal tape shield wrap. Fold the earth lead back over the roll spring. Wrap the rest of the roll spring around the earth lead. Carefully slide the roll spring and earth lead down into the crutch until it is about 10 mm from the end of the oversheath. Tighten the roll spring with a twisting action and fix it into place with two layers of adhesive tape.

2

Clean and degrease the end of the oversheath for a length of 1 metre with solvent wipe.

Cut the core according to the dimension given in the drawing. Remove the core screen with appropriate screen cutting tool according to the drawing. The surface of the insulation should be free from all traces of conductive material. Compare the diameter over insulation with application range as shown in Table 1 as well as with marking of supplied stress cone. Application Check!

4

3

Cable with wire shield Position the cable with sufficient overlap to the bushing centre. Mark the oversheath 255 mm below the bushing centre. Cut the cable 600 mm above the mark and remove the oversheath over this distance. Cut off Cu-spiral screening tape flush with end of outer sheath. Edges projecting beyond the outer sheath must be avoided, so that the stress cone can not be damaged during push on procedure.

Cut back the insulation according to dimension K given in drawing details. A. Hexagonal and deep indent compression lugs Dimension K must not exceed 60 mm. B. Mechanical lugs Dimension K is identical to depth of bore. Barrel butts against insulation!

5

Wrap one turn of sealant tape (grey) with no overlap and slight tension around the end of the oversheath. Cut the tape and push ends together. Bend the shielding wires back onto the oversheath. Avoid crossing the individual wires. Temporarily secure the wires with a tape or wire binder.

Recommendation for large cross sections Convenient push on process of the stress cone requires chamfering of the insulation for cross section 240 mm² and above. See drawing!

Slide the small protective bag (assembly aid) over the exposed conductor and tie it down with a PVC tape as shown in the drawing. Gently lubricate the outer surface of the protective bag and the core insulation with a thin layer of assembly lubricant Apply the lubricant layer with the sponge top as shown.

B. Mechanical lugs with inserts

A. Compression lugs Install the cable lug with the appropriate die and compression tool. Note: Remove any sharp edges. Clean and degrease the lug and insulation from any excessive compression grease.

9a

The insert has to be used as noted in Table 2.

Apply onto the inner surface of the stress cone at the bottom end a 3 cm long sausage of assembly lubricant and spread it evenly over the inner surface. Use assembly lubricant without sponge top. Push the stress cone in one sequence with a twisting movement over the assembly aid completely onto the insulation until the inner collar of the stress cone stops at the oversheath cut back of the cable. Note: The arrow on the stress cone should point onto the cable sheath. Remove the assembly aid from the conductor.

Ensure that the retention of the insert is locked into the appropriate slot in the barrel. Install the cable lug using a lug fixture. Tighten the bolt set alternately in several equal steps until the heads shear off. Remove any sharp edges.
