COMPAQ 11kV 3C 185sqmm Indoor Termination Kit (or equivalent 11 kV, 3-core, 185 sq mm indoor termination kit), including typical application, components and features. This should help for your technical documentation or project spec.
A termination kit is used to end (terminate) a medium-voltage cable and connect it safely to switchgear, transformer terminals, or other electrical equipment in a manner that ensures insulation, mechanical protection, and safety.
This kit is designed for 11 kV systems and 3-core cables with conductor cross-section of 185 sq mm (XLPE / PILC or similar insulated cables).
It is intended for indoor use e.g. inside substations, indoor switchgear rooms, or other controlled environments.
Based on standard 3-core 11 kV kits (and documentation from producers/manufacturers including similar kits) the termination kit for 3C 185 sq mm typically includes:
| Component / Material | Purpose / Function |
|---|---|
| Heat-shrinkable outer jacketing sleeve (2 nos) | Provide outer insulation, mechanical protection & environmental sealing after termination. |
| Heat-shrinkable stress-control tubing (3 nos) | To control electrical stress at the cut end of the conductor insulation avoids partial discharge and ensures insulation integrity. |
| Heat-shrinkable insulating tubing (3 nos red or required colour) | Provide insulation over individual cores and phase separation. |
| Dual-wall tubing (red & black, where applicable) | Combines insulation with moisture sealing / environmental protection, where needed. |
| G.I. mesh and armour/metal-screen earthing arrangement (including copper braid, mesh tape, rings, clamps, binding wire, solder flux, etc.) | For earthing / screening / shielding of cable armour or metallic screen ensures proper grounding and safety. |
| Stress-control mastic / sealing compounds / tapes / PVC adhesive tape | For sealing joints, filling voids, ensuring moisture-proof insulation and preventing environmental ingress. |
| Connector / mechanical / bolted / crimp lugs or ferrules (as per conductor type: aluminium or copper) | To connect the cable conductor to the equipment terminal or busbar securely. Some kits use mechanical shear-bolt cable lugs for secure connection. |
| Installation instructions & cleaning materials (e.g. emery paper, cloth, cleaning tissue, grease) | For proper cable preparation, insulation cleaning, and installation quality. |
Voltage rating: 11 kV medium-voltage suits typical distribution/substation cables.
Cable compatibility: 3-core, 185 sq mm XLPE (or suitable insulation) cables armour or screened cables are also manageable with earthing/screening provisions.
Insulation & stress control: Heat-shrink stress-control tubing and insulating sleeves ensure safe termination prevents partial discharge, flashovers, and enhances long-term reliability.
Moisture / environmental protection: Outer jacketing, sealing tapes, mastics protect against humidity, dust, moisture ingress (especially important if indoor environment is not climate-controlled).
Mechanical and electrical safety: Proper earthing of metallic screen/armour, secure lug/connector connection, strong insulating barrier ensures safety of equipment and personnel.
Ease of installation: Pre-engineered kit with all necessary materials; heat-shrink tubing allows reasonably quick installation (though requires correct procedure) compared to bespoke termination.
Make sure the cable type (XLPE, PILC, screened or armoured) matches kits specification. Not all kits may support all insulation/armour types.
Use correct lugs / connectors compatible with your cable conductor (copper or aluminium). Some kits are designed for mechanical shear-bolt lugs.
Ensure proper stress-control installation and cleaning / preparation of cable ends before applying shrink sleeves poor installation can lead to insulation failure or partial discharge.
For indoor application: ensure proper earthing/grounding if cable is screened or armoured, and maintain environment dryness (moisture ingress can degrade insulation over time).
Follow relevant standards / specifications (IEC / IS / relevant Indian grid norms) for 11 kV cable terminations.
