Elastimold Cable Terminations – High Voltage Silicone Shrink-Fit Terminations

Elastimold Cable Terminations - High Voltage Silicone Shrink-Fit Terminations

Elastimold Cable Terminations – High Voltage Silicone Shrink-Fit Terminations

Elastimold High Voltage Silicone Shrink-Fit Terminations are manufactured using an optimised weather-resistant silicone formulation and offer superior cable sealing and voltage withstand characteristics.

Elastimold silicone shrink-fit terminations have three different shed designs for superior weathering – 15kV, 25/28kV and 35kV, accommodating cables ranging from #2 AWG to 1250 kcmil and cable types such as XLPE and EPR with various shield constructions.

Integral Hi-K voltage stress control tubes provide uniform voltage grading over the length of the termination and eliminates damaging voltage stress concentrations at the cable insulation shield edge. The lightweight, compact design allows installations where space is restricted and can be used within free hanging applications.

Installation Instructions

Elastimold Cable Terminations - High Voltage Silicone Shrink-Fit Terminations 2

Step 1. Train the cable into position and cut to length. Using standard practices, cut back the cable jacket, metallic shield, semi-conductive shield and cable insulation, exposing the conductor.

Step 2. Finish preparing the metallic shield. For concentric neutral or jacketed concentric neutral cables, bend back the neutral wires and seal with mastic strips and vinyl tape. For metallic tape, drain wire, UniShield or LC Shield cables: install the ground braid using the constant force spring and seal with mastic strips and vinyl tape.

Step 3. Clean the exposed conductor, install and crimp the connector.

Step 4. Use mastic and vinyl tape to fill any gap or step between the connector and the cable insulation. Clean the cable.

Step 5. Apply a liberal bead of silicone lubricant to the semi-con shield step.

Step 6. Pull the loose end of the core cord until the core is even with the end of the termination housing.

Step 7. Position the cable terminator onto the cable.

Step 8. Shrink cable termination into place by unwinding the removable core.

Step 9. Apply silicone lubricant to skirt and mastic area.

Step 10. Fold down the skirt over the mastic to seal the cable entrance.

Step 11. Seal the top of the cable terminator at the connector area with silicone tape.

Step 12. Attach the neutral wires or optional ground braid to the system ground per local code. Install the optional cable support bracket if required.
