Heat Shrinkable Cable Accessories

The production of heat shrinkable cable accessories needs to go through a series of processes such as Mixing → Forming → Irradiation → Expansion → Gluing. Shape memory effect of polymer materials is the basic principle of fabricating heat-shrinkable materials. The characteristics of the polymer material itself give the heat shrinkable cable accessories with good electrical and mechanical properties, light weight, easy installation and other advantages. 

The heat shrinkable cable accessories products are waterproof, stress control, shielding, insulation in one, can be used in a variety of harsh environmental conditions for a long time. They are widely used in Electric Power Industry, Petroleum Industry, Chemical Industry, Metallurgy, Railway, Port, Construction and other fields.


The most important part of heat shrinkable cable accessories is Stress control tube. Heat shrinkable stress control tube refers to a casing used to shield the electrical stress at the termination of a cable.  A new theory of stress control for high voltage cable terminal is developed, and a heat shrinkable stress control tube with appropriate impedance value is developed.  Heat shrinkable stress control tubes can be prepared for cables with different voltages and cross sections. The test proves that the electrical and thermal properties are stable and reliable even after regular operation. The cable terminal designed by heat-shrinkable semiconductor stress control tube can meet various test standards. Every part of Heat shrinkable Cable Accessories are important.


HUYI in accordance with the brand of The heat shrinkable cable accessories products through constant research and development of science and technology, has reached the domestic and international most advanced level, at home and abroad enjoys a high reputation, the products sell well all over the country and world.

  • The Water-proof sealing Mastic has excellent bonding properties to metal and various cable sheath materials; For irregular surface has good shape, and can be molded; Good compatibility with various cables; Chemical resistance; Wide temperature range, and maintain its excellent sealing performance; Repeated bending without cracking; When punctured, it shows excellent self-healing properties. It is flexible and easy to operate at low temperatures.

  • The Shielding Earth Braid is used to isolate electromagnetic field noise sources from sensitive devices and cut off the propagation path of the noise sources. Shielding Earth Braid is divided into active shielding and passive shielding. Active shielding is to prevent noise sources from radiating outward. Passive shielding is designed to prevent sensitive equipment from being interfered by noise sources.

  • The Copper Shield Tape has low surface oxygen characteristics and can be attached to a variety of different substrates, such as metal, insulating materials, etc., with a wide temperature range. Mainly used in electromagnetic shielding and antistatic, the conductive copper foil on the substrate surface, combined with the metal substrate, has excellent conductivity, and provide electromagnetic shielding effect.

  • The Filling Mastic is used for crosslinking wire and cable terminal box joint, filling insulation, gas, water and sealing. Specially used in power cable terminal accessories. It has an independent factory site with the building area of 27000 square meters, the land area of more than 14300 square meters. Product testing equipment is complete, with nano electron accelerator, injection moulding machine, rubber molding machine and other production and manufacturing equipment.

  • The Heat Shrinkable Rainshed is made of electric-mark resistant polyolefin material and coated with electric-mark resistant and weather-resistant sealant. Specially used in power cable terminal accessories. It has an independent factory site with the building area of 27000 square meters, the land area of more than 14300 square meters. Product testing equipment is complete, with nano electron accelerator, injection moulding machine, rubber molding machine and other production and manufacturing equipment.

  • The Heat Shrinkable Insulation Tape are made of crosslinked polyolefin material and environmental protection hot melt adhesive. It is wound around the damaged place of copper bar or cable, and will shrink when heated. The heat shrinkable melt of inner wall will stick the covering tape and copper bar (cable) tightly, playing a waterproof role.
