The definitive guide to heat shrink cable termination kits for XLPE, PVC and PILC cables from 1.1kV to 36kV — covering types, IS 13573 standards, selection criteria, installation steps and why VIKCHEM's IS/IEC-certified kits outperform imported alternatives for Indian utilities and EPC contractors.
What Is a Heat Shrink Cable Termination Kit?
A heat shrink cable termination kit is a pre-engineered assembly of heat-activated polymeric components that safely terminates power cables at the connection point to electrical equipment — transformers, switchgear panels, ring main units and overhead lines. When heated, the materials shrink tightly around the cable, creating a moisture-proof, UV-resistant, electrically insulated seal that protects the cable end throughout its service life.
VIKCHEM has manufactured heat shrink cable termination kits since 1988 — making us one of India's oldest and most trusted manufacturers of cable accessories. Our kits are certified to IS 13573 and IEC 60502 and are trusted by Indian Railways, NTPC, BHEL, DHBVN and 1000+ power utilities across India.
Types of Heat Shrink Cable Termination Kits
Indoor Heat Shrink Termination Kits
Designed for transformer rooms, switchgear panels and indoor substations up to 36kV. Compact profiles fit space-constrained installations. Feature single-layer stress control and phase-identified heat shrink tubing. Compatible with XLPE, PVC, PILC and EPR cables in single-core, 3-core and 3.5-core configurations.Outdoor Heat Shrink Termination Kits
Engineered for pole-mounted transformers, cable sealing ends and overhead-to-underground transitions. UV-stabilised silicone rubber sheds, enhanced tracking resistance and weatherproof sealing protect against India's monsoon rains, coastal salt air and industrial pollution. Available for 11kV, 22kV and 33kV systems.Straight Boot Terminations
The most common configuration for vertical cable terminations to distribution transformers. Provide excellent insulation coordination at 11kV to 33kV.Elbow (Angle Boot) Terminations
Pre-moulded elbow connectors for right-angle connections to padmount transformers and compact switchgear. Space-saving for congested electrical enclosures. The touch proof version eliminates exposed live conductors entirely.Voltage Ratings and Cable Compatibility
| Voltage | Cable Types | Application |
| 1.1kV | XLPE, PVC, PILC | LV distribution boards, motor control centres |
| 11kV | XLPE, PVC, PILC, EPR | Distribution transformers, RMUs, switchgear |
| 22kV | XLPE, PILC | Sub-transmission, bulk supply points |
| 33kV (36kV) | XLPE, PILC | Grid substations, major industrial installations |
IS 13573 and IEC 60502 Certification — Why It Matters
Imported termination kits from brands like 3M Raychem are tested to European standards. VIKCHEM's kits are additionally type-tested to IS 13573 — the Indian Standard for joints and terminations for polymeric insulated cables. This matters because:
- ●Government tenders (DISCOM, Railways, PSUs) specify IS 13573 compliance
- ●IS-certified products qualify for Make in India preference in public procurement
- ●Local manufacturing means faster delivery and full technical support in India
- ●ZeD Gold certification demonstrates zero-defect manufacturing commitment
- ●IS 13573 certified — mandatory for many Indian government and utility tenders
- ●38+ years of manufacturing in India — superior understanding of Indian grid conditions
- ●Price competitive — no import duties, duties-free pricing vs 3M/Raychem imports
- ●Faster delivery — ex-stock from Yamuna Nagar, Haryana — delivered anywhere in India within 3–7 days
- ●Technical support — Indian engineers available for installation guidance
- ●1000+ clients including Indian Railways, NTPC, BHEL, L&T, Power Grid Corporation
- ●Distribution transformers (pole-mounted and pad-mounted)
- ●Ring main units (RMU) and compact secondary substations
- ●Metal-clad switchgear up to 36kV
- ●Solar farm and wind power cable connections
- ●Metro and railway electrification cable terminations
- ●Industrial plant power distribution systems
Selection Criteria
Step 1 — Cable Type: Identify whether your cable is XLPE, PVC, PILC or EPR. Each requires a kit with compatible material interfaces. XLPE is the modern standard; PILC transition kits are available for legacy networks.
Step 2 — Voltage Rating: Never select a kit rated below your system voltage. For 33kV systems, use a 36kV-rated kit to include margin.
Step 3 — Indoor vs Outdoor: Outdoor kits must have UV-stabilised, weatherproof materials. Indoor kits can use more compact configurations.
Step 4 — Number of Cores: 3-core and 3.5-core cables require a different kit geometry from single-core. Select correctly.
Step 5 — Conductor Cross-Section: Kits are sized for specific conductor ranges (e.g. 35–400 mm²). Match the conductor size.
Installation Process — Step by Step
1. Prepare cable — cut to length, strip outer jacket, armour and screens to manufacturer dimensions 2. Install earth/screen connections — connect earth braids and screen wires per kit instructions 3. Apply stress control tube — critical for all medium voltage cables to manage electric field 4. Position heat shrink components — slide components onto cable; ensure correct overlap 5. Apply heat evenly — use appropriate heat gun, start from centre working outwards 6. Install phase identification — apply phase colour-coded tubing (Red/Yellow/Blue) 7. Fit cable lugs and complete termination — torque to specification 8. Inspect — verify all components fully shrunk, no air bubbles or lifted edges
Installation time: 60 minutes for a standard 3-core 11kV termination.

Frequently Asked Questions
Q: What is the difference between indoor and outdoor heat shrink termination kits? Outdoor kits use UV-stabilised, weatherproof silicone rubber with shed profiles to shed rain. Indoor kits use compact straight designs without sheds. Never use an indoor kit outdoors.
Q: Can VIKCHEM termination kits be used with both XLPE and PILC cables? Yes — VIKCHEM manufactures separate kits for XLPE, PILC, PVC and EPR cables. Always specify your cable type when ordering.
Q: Are VIKCHEM kits approved for Indian Railways contracts? Yes. VIKCHEM's cable accessories are supplied to Indian Railways and meet all relevant IS standards required for Railway contracts.
Q: What tools are needed for installation? Standard cable preparation tools, a heat gun (300–500°C), torque wrench and basic hand tools. No specialised equipment is required.
