10kV Heat Shrink Cable Termination Kit — Reliable Manufacturer & Supplier
Medium-voltage power failures are often traced back to poor cable terminations. The Zhizheng RSY-10 Series (6/10kV & 8.7/15kV) heat shrink cable termination kits are engineered to eliminate these risks. Manufactured in our 40,000㎡ ISO-certified facility in Hubei, China, our kits deliver exceptional stress control, weather resistance, and insulation performance. Whether you need the NRSY series for indoor switchgear or the WRSY series with extended rain skirts for outdoor substations, buying factory-direct ensures you get certified quality at competitive wholesale prices.
Product Overview
The RSY-10 Series includes premium heat-shrinkable terminal accessories designed specifically for 10kV (up to 15kV) medium-voltage Cross-Linked Polyethylene (XLPE) power cables. Complying strictly with GB/T 12706, JB/T 8144, and DL/T 413 standards, these kits utilize radiation-crosslinked polymeric materials that offer permanent elastic memory. They provide a seamless, moisture-proof seal that guarantees long-term stable operation in extreme environments ranging from -40°C to +105°C.
Key Features & Business Benefits
Exceptional Insulation Safety: Achieves a partial discharge of ≤2pC (far exceeding the standard ≤20pC requirement), significantly reducing the risk of insulation breakdown and extending cable life.
Tailored for Any Environment:
Indoor (NRSY-10): Compact design perfect for confined spaces like switchgear and indoor transformers.
Outdoor (WRSY-10): Equipped with specialized anti-tracking rain sheds (skirts) to increase creepage distance and resist heavy pollution and UV rays.
Fast & Foolproof Installation: Designed for rapid, uniform heat shrinking. Ensures a secure fit over XLPE cables without the need for specialized heavy tooling.
Verified Durability: Successfully passed 20 rigorous load cycles at 90°C with zero breakdowns, ensuring grid reliability under peak power demands.
Cost-Effective Bulk Sourcing: As a direct China manufacturer, we provide flexible OEM customization, private labeling, and scalable volume production for global EPC contractors and distributors.

FAQ
Q1: What is the main difference between the NRSY-10 (Indoor) and WRSY-10 (Outdoor) kits?
A: The WRSY-10 outdoor terminations include additional heat-shrinkable rain sheds (skirts). These sheds significantly increase the creepage distance, preventing electrical tracking caused by rain, salt fog, and industrial pollution.
Q2: What is included in a standard 10kV heat shrink termination kit?
A: A complete kit typically includes stress control tubing, anti-tracking insulation tubing, breakout boots (for 3-core cables), sealing mastics, rain sheds (for outdoor versions), and a detailed installation manual. Copper or aluminum lugs can be provided upon request.
Q3: Can these kits be used on older PVC cables, or only XLPE?
A: The RSY-10 series is specifically optimized for Cross-Linked Polyethylene (XLPE) medium-voltage cables. If you have specific requirements for other insulation types, please contact our engineering team for a customized solution.
Q4: Do you support factory-direct wholesale and OEM branding?
A: Absolutely. As a direct manufacturer with over 20 years of experience in Hubei, China, we offer flexible bulk wholesale pricing, custom kitting, and private labeling (OEM) for global distributors and EPC contractors.
