A state-wise guide to selecting IS 13573 certified heat shrink cable termination kits, cable jointing kits, and power cable accessories for Indian DISCOMs — UPPCL, MSEDCL, TNEB, WBSEDCL, PSPCL, HVPNL, CSPDCL and more. Covers approved specifications, common voltage levels, and how to procure from VIKCHEM — manufacturer in Yamuna Nagar, Haryana.
Who Makes Heat Shrink Cable Accessories for India's Power Distribution Companies?
India's power distribution network is one of the largest in the world — over 4 million kilometres of HT and LT lines, managed by more than 60 state DISCOMs and utilities. Every underground cable in this network — whether it runs beneath a Delhi street or connects a rural feeder in Chhattisgarh — requires cable accessories: termination kits, jointing kits, and end sealing products that protect conductors from moisture, mechanical damage, and electrical stress.
Vikram Power Technologies Pvt. Ltd. (VIKCHEM), based in Yamuna Nagar, Haryana, has been manufacturing IS 13573 certified heat shrink cable termination kits, straight-through jointing kits, and power cable accessories for Indian utilities since 1988 — over 38 years of continuous supply to DISCOMs, Railways, NTPC, BHEL, L&T, and 1,000+ contractors across 20+ countries.
This guide answers one specific question for procurement engineers, project managers, and EPC contractors: which cable accessories do Indian state DISCOMs use, at what voltage levels, and where can you source IS-certified products reliably?

Why Indian DISCOMs Specify Heat Shrink Over Other Technologies
Heat shrink cable accessories dominate DISCOM procurement in India for three reasons:
1. IS 13573 and IEC 60502-4 Certification India's Bureau of Indian Standards mandates IS 13573 compliance for cable accessories used in utility-grade installations above 1.1kV. Heat shrink technology — when manufactured correctly — consistently meets these standards. Cold shrink and push-on accessories remain niche in the Indian DISCOM market primarily because of temperature performance issues during peak Indian summers (45°C+ ambient in Rajasthan, UP, MP, and Gujarat).
2. Installation Speed DISCOM line crews work under pressure — outage windows are short, and gang sizes are small. Heat shrink kits require no special tools beyond a standard propane or LPG torch and can be installed in 45–90 minutes per joint by a trained crew, compared to 3–5 hours for cold pour resin joints. This directly reduces outage duration and restoration costs.
3. Long Service Life Properly installed heat shrink accessories from IS 13573 certified manufacturers deliver 25–30 year service life — matching the lifecycle of modern XLPE cables. This matters to DISCOMs under capex pressure: you only want to dig up a cable trench once.

Tamil Nadu — TANGEDCO / TNEB
TANGEDCO (Tamil Nadu Generation and Distribution Corporation) manages one of South India's most urbanised distribution networks, with active underground cabling in Chennai, Coimbatore, Madurai, Salem, and Tirupur.
Voltage levels: 11kV (predominant), 22kV, 33kV
Special requirement: TANGEDCO specifications emphasise UV resistance and high ambient temperature performance — critical in Tamil Nadu's coastal and hot climate. Heat shrink termination kits must demonstrate tracking resistance and moisture seal performance to IS 13573 under accelerated ageing conditions.
Common cable types used: XLPE armoured cables (Aluminium conductor), 3-core and single-core configurations
Key project driver: Tamil Nadu has one of India's largest underground cable programmes under 100% electrification and Smart Grid initiatives. Coimbatore, Tirupur, and Chennai districts have seen significant underground expansion since 2022.
---
West Bengal — WBSEDCL and CESC
West Bengal's distribution is split between WBSEDCL (rural and semi-urban areas) and CESC (Kolkata and surrounding districts).
Voltage levels: 11kV (most common), 33kV (sub-transmission)
Climate consideration: West Bengal's high humidity and monsoon conditions make moisture-proof sealing critical. XLPE/PILC transition joints are commonly needed in older Kolkata grid areas where legacy PILC cables are still in service. VIKCHEM's XLPE/PILC transition straight-through jointing kits are purpose-built for exactly this application.
Key specification: WBSEDCL follows IS 13573 and requires factory test certificates with each supply. CESC maintains its own vendor qualification list and requires pre-qualification for direct supply.

Gujarat has one of India's highest industrial cable densities — GIDC (Gujarat Industrial Development Corporation) estates in Surat, Vadodara, Ahmedabad, Vapi, Ankleshwar, and Rajkot require large volumes of 11kV and 33kV cable accessories annually.
Key differentiator: Gujarat DISCOMs and GIDC industrial connections frequently specify outdoor-rated termination kits with enhanced UV and pollution resistance — VIKCHEM's outdoor heat shrink termination kits carry IS 13573 Part 3 (outdoor) certification and have been tested for tracking resistance under IEC 60587.
---
Karnataka — BESCOM, MESCOM, HESCOM, GESCOM, CESC
Karnataka's distribution network is among the most technically progressive in India. BESCOM (Bangalore Electricity Supply Company) is particularly active in underground cabling, driven by Bengaluru's rapid urban expansion.
Voltage levels: 11kV (most common for underground distribution), 33kV (feeder connections)
BESCOM specification: BESCOM requires IS 13573 type test certificates and insists on correct kit selection based on cable cross-section — particularly for the diverse cable sizes found in Bengaluru's mixed-age grid (from 35 sqmm feeders in older areas to 240 sqmm and 400 sqmm in new zones).
VIKCHEM's product range covers all cross-sections from 16 sqmm to 630 sqmm at 11kV and 33kV — ensuring a single supplier can cover all project requirements.
