At Jihui Electric Group Co., Ltd., we focus on developing and manufacturing reliable medium and low voltage power transmission and distribution equipment up to 35kV. With professional experience in Cable accessories, switchgear, transformers, and complete power solutions, we provide products that support modern electrical networks in different industries.

The 35kV three core intermediate connection accessory is one of our important Cable Accessory products designed for medium voltage cable connection applications. It is developed to help customers achieve safe, stable, and long-lasting cable connections in power distribution systems.

During years of working with power companies, engineering contractors, industrial customers, and renewable energy projects, we have learned that a cable connection point needs more than simple connection performance. It must provide strong insulation, reliable sealing, mechanical protection, and stable operation under different environments.

Based on these requirements, we manufacture our 35kV three core intermediate connection accessory with advanced materials, strict production control, and practical engineering experience. Our goal is simple: provide customers with a cable joint solution they can trust for many years.

Product Overview of 35kV Three Core Intermediate Connection Accessory

The 35kV three core intermediate connection accessory is designed for connecting two sections of three-core 35kV power cables. It restores the cable insulation structure and provides protection after cable jointing.

In medium voltage power systems, cable joints play an important role because they directly affect the reliability of electricity transmission. A high-quality cable connection accessory helps maintain electrical performance and reduce possible operation problems.

Our 35kV intermediate connection accessory is widely used in:

• Medium voltage power distribution networks

• Underground cable systems

• Industrial electrical projects

• Renewable energy power plants

• Infrastructure construction projects

The product combines insulation recovery, stress control, sealing protection, and mechanical strength into one complete solution.

Why We Developed This 35kV Cable Connection Solution

When designing cable accessories, we always consider real project conditions. In actual power systems, cable joints may face moisture, temperature changes, mechanical pressure, and continuous electrical stress.

A poor-quality cable connection can influence the stability of the whole power network. Therefore, we focus on improving three key areas:

• Electrical reliability: maintaining stable insulation performance under 35kV voltage conditions.

• Environmental protection: preventing moisture and dust from entering the cable connection area.

• Installation convenience: making installation easier for engineering teams.

The 35kV three core intermediate connection accessory is created to solve these practical challenges and provide a dependable cable jointing solution.

Working Principle of 35kV Three Core Intermediate Connection Accessory

The working principle of a cable intermediate connection accessory is based on rebuilding the original cable structure after two cable sections are connected.

During installation, technicians first prepare the cable ends according to technical requirements. After conductor connection is completed, the intermediate accessory is installed around the cable joint area.

The insulation layer provides electrical protection, while the sealing structure prevents external moisture and contamination from entering.

The main working functions include:

• Electrical insulation restoration

• Electric field stress control

• Waterproof sealing protection

• Mechanical reinforcement

• Long-term cable operation support

Through proper design and manufacturing control, our cable connection accessory helps maintain stable performance during the service life of the power system.

Main Features of 35kV Three Core Intermediate Connection Accessory

1. Excellent Insulation Performance

Insulation performance is one of the most important factors for Medium Voltage Cable Accessories. Our product uses high-quality insulation materials designed for stable electrical performance.
