33kV 3 Core Outdoor Heat Shrink Cable Termination Kit

Compared with lower-voltage cable systems, 33kV power networks require higher insulation performance and more precise stress control because the cable termination area experiences stronger electrical field intensity after cable preparation.

Manufactured by GOTOELE, a professional electrical equipment supplier in China, this 33kV outdoor cable termination kit is developed for industrial power systems, utility networks, renewable energy projects and infrastructure applications where long-term operational reliability is essential.

Designed for High Voltage Cable Network Reliability

1. Stable Insulation Performance Under 33kV Voltage Stress

The insulation tubes included in the kit restore the original insulation protection after the cable conductor and shielding layers are processed during installation.

The heat shrinkable insulation structure tightly bonds with the cable surface after heating, providing reliable electrical separation between:

· Three phase conductors

· Cable shielding layer

· Grounding system

This design helps maintain insulation performance during continuous operation in 33kV power distribution systems.

2. Multi-Layer Outdoor Protection for Harsh Environments

The outdoor insulation sheds are designed to increase surface creepage distance and improve environmental resistance.

They help protect the cable termination from:

· Heavy rainfall

· High humidity

· Dust contamination

· Industrial pollution

· Temperature variations

This makes the product suitable for outdoor installation areas where cable accessories are exposed to changing environmental conditions.

3. Controlled Electric Field Distribution at Cable Termination Points

At 33kV voltage levels, uneven electric field distribution at cable termination points may increase the risk of partial discharge and insulation deterioration.

The stress control components and shielding materials in the kit help smooth electrical field distribution around the cable cut area, reducing electric field concentration and improving long-term cable system stability.

4. Reliable Sealing Structure for Long-Term Operation

The three-way branch glove provides additional sealing protection at the cable branch section.

Together with sealing mastic and heat shrink materials, it creates a closed protective structure that helps prevent:

· Moisture penetration

· Water ingress

· Dust contamination

This improves the reliability of outdoor cable connections throughout the service period.

Global Application Case

33kV Industrial Facility Power Upgrade Project

A manufacturing facility in Southeast Asia upgraded its electrical system by adding a new 33kV power supply line. The 33kV 3 Core Outdoor Heat Shrink Cable Termination Kit was selected for outdoor cable terminal connections between switchgear and transformer equipment.

The project required cable accessories capable of operating under high humidity, frequent rainfall and continuous industrial power demand.

After installation, the termination system provided stable insulation performance and reliable sealing protection, helping improve the operational stability of the site's high-voltage power distribution network.

Project Details:

· Application: Industrial 33kV power distribution upgrade

· Cable type: Three-core XLPE insulated power cable

· Installation location: Outdoor switchgear and transformer connection points

· Main requirements: High-voltage insulation, waterproof sealing and environmental resistance

Installation Considerations for 33kV Cable Termination

Because 33kV cable systems operate under higher electrical stress, professional installation is essential to achieve the expected service performance.

Important installation factors include:

· Accurate cable stripping dimensions according to installation requirements

· Correct installation of stress control components

· Complete sealing treatment at cable joints and branch sections

· Clean installation environment to prevent contamination

· Proper heating process during heat shrink installation

Following standardized installation procedures helps ensure long-term reliability of the cable termination system.

Compatible Cable Types and Operating Environment

The 33kV 3 Core Outdoor Heat Shrink Cable Termination Kit is designed for outdoor termination of 33kV three-core XLPE insulated power cables.

Compatible cable models include:

· YJV
