10kV 3 Core Outdoor Heat Shrink Cable Termination Kit

During the installation of medium-voltage power cables, the cable termination area is one of the most critical points because the original cable insulation and shielding layers are exposed after processing. Without proper protection, moisture penetration, uneven electric field distribution and insulation aging may affect the long-term safety of the power system.

Developed and manufactured by GOTOELE, a professional electrical equipment supplier in China, this 10kV outdoor cable termination kit integrates heat-shrink insulation materials, stress control components and sealing accessories to ensure stable operation in outdoor power distribution environments. It is widely used in municipal power grids, industrial facilities, infrastructure projects and commercial electrical systems.

Engineering Design and Functional Structure

1. Heat Shrink Insulation Protection

The three long reddish-brown heat shrink tubes are designed to cover the stripped main insulation sections of the three cable cores. After heating, the tubes shrink tightly around the cable surface, creating a strong insulation layer with excellent electrical performance and mechanical protection.

This structure helps maintain the insulation level between conductors and provides reliable protection against environmental exposure during long-term operation.

2. Outdoor Anti-Pollution Insulation Sheds

The integrated reddish-brown insulation sheds are specially designed for outdoor applications. They increase the creepage distance of the cable termination surface and improve resistance against rain, humidity, dust and industrial pollution.

Compared with indoor cable terminations, outdoor termination structures require additional protection because they are directly exposed to weather conditions. The anti-pollution sheds help reduce the risk of surface flashover caused by moisture and contamination.

3. Electrical Stress Control System

When a high-voltage cable is cut and terminated, the electric field distribution around the cable end changes significantly. Concentrated electric stress may cause partial discharge or insulation failure if not properly controlled.

The 10kV 3 Core Outdoor Heat Shrink Cable Termination Kit uses stress control materials and shielding components to optimize electric field distribution, reduce stress concentration at the cable cut point and improve the reliability of the complete termination system.

4. Three-Core Branch Sealing Structure

The black three-way branch glove is installed at the cable branching section. It provides sealing protection for the transition area between the cable outer sheath and individual cable cores.

By tightly covering the branching point, it prevents rainwater, moisture and dust from entering the cable structure, improving the overall waterproof performance of the termination.

5. Complete Installation Accessories

The kit includes all necessary auxiliary materials required for professional cable termination installation, including:

· Aluminum foil shielding tape for electrical field distribution and shielding connection

· Sealing mastic for filling gaps and preventing moisture penetration

· Phase identification sleeves for easy identification of A/B/C phases

· Lubricant packets for installation assistance

· Protective gloves and installation instructions for construction convenience

The complete accessory package helps improve installation efficiency and maintain consistent termination quality.

Applicable Cable Types and Installation Environment

The 10kV 3 Core Outdoor Heat Shrink Cable Termination Kit is designed for 10kV three-core XLPE insulated power cables, including commonly used cable models such as:

· YJV

· YJV22

The product is specifically designed for outdoor environments with direct exposure to weather conditions.

Because it is equipped with outdoor anti-pollution sheds, it should be used for open-air cable termination applications. Indoor cable termination systems without weather exposure requirements should use corresponding indoor termination solutions.

Global Application Case

Southeast Asia Industrial Power Distribution Project

The 10kV 3 Core Outdoor Heat Shrink Cable Termination Kit was applied in a manufacturing plant power distribution project in Southeast Asia for outdoor 10kV cable terminal connections between switchgear and transformer equipment.

Due to the local high temperature, heavy rainfall and humid environment, the project required reliable waterproof sealing and long-term insulation protection. The heat shrink termination kit provided stable performance by combining stress control technology, outdoor insulation sheds and sealing materials.

After installation, the cable termination system operated reliably under continuous industrial power supply conditions, helping reduce maintenance requirements and improve power distribution safety.

Project Details:

· Application: 10kV industrial power distribution system

· Cable type: Three-core XLPE insulated power cable

· Installation: Outdoor switchgear and transformer cable terminals

· Key requirements: Waterproof sealing, insulation reliability and weather resistance
