35kV Heat Shrink Cable Termination Kit — High-Voltage Solutions Manufacturer

High-voltage power transmission requires uncompromising electrical stress management. The Zhizheng RSY-35 Series (21/35kV & 26/35kV) heat shrink terminations are engineered specifically for heavy-duty infrastructure. Produced in our 40,000㎡ facility in China, these kits provide superior mechanical protection and electrical insulation for critical networks, including renewable energy substations and heavy industrial plants. By partnering directly with the manufacturer, global EPC contractors gain access to premium, type-tested 35kV accessories at highly competitive wholesale rates.

Product Overview

The RSY-35 Series serves as the ultimate connection solution for 35kV Cross-Linked Polyethylene (XLPE) power cables. Built to comply with GB/T 12706.4, JB/T 8144, and DL/T 413 standards, the kits feature high-grade, lightweight polymeric materials. Whether deploying the NRSY-35 for indoor switchgear or the WRSY-35 for outdoor exposed environments, the system ensures long-term operational stability in extreme temperatures (-40℃ to +105℃).

Key Features & Engineering Advantages

  • Heavy-Duty Dielectric Strength: Tested to withstand a 250kV impulse voltage (10 times, positive/negative), ensuring grid resilience against lightning strikes and power surges.

  • Ultra-Low Partial Discharge: While industry standards require ≤10 pC at 39kV, our combined sample testing yielded a remarkable 4.5 to 4.8 pC, indicating a virtually flawless insulation structure.

  • Advanced Stress Control: High-voltage cables generate intense electrical fields at the termination cut-back. Our specially formulated stress-control tubing disperses this energy safely, preventing premature cable breakdown.

  • Weather & Tracking Resistance: The outdoor WRSY-35 models are equipped with heavily engineered anti-tracking rain skirts, shedding water and combating heavy industrial pollution and salt fog.

  • Optimized for B2B Supply Chains: We offer streamlined manufacturing for bulk purchasing, private OEM labeling, and custom dimensional adjustments for specialized high-voltage projects.

Frequently Asked Questions

Q1: Why is stress control more critical for the 35kV kits compared to 10kV?

A: At 35kV, the electrical field concentration at the end of the cable shield is significantly higher. Our RSY-35 kits include highly specialized stress-relief tubing with precise impedance characteristics to manage and disperse this stress, preventing high-voltage tracking and failure.

Q2: Are these 35kV terminations suitable for renewable energy projects?

A: Yes. The WRSY-35 outdoor terminations are widely specified by EPC contractors for wind turbine step-up transformers and solar farm grid-tie connections due to their extreme UV resistance and 250kV impulse durability.

Q3: What is your manufacturing lead time for large 35kV project orders?

A: For standard sizes, our automated facilities in Hubei can dispatch orders within 10 to 20 days. For custom OEM specifications or massive infrastructure quantities, lead times are typically 20 to 30 days. We maintain safety stock to support urgent project timelines.

Q4: Can we order these kits with our own company branding (OEM)?

A: Absolutely. As a direct factory supplier, we provide full OEM packaging and private labeling services for electrical distributors and brand owners worldwide.
