☆Production Capacity
HUAYI CABLE ACCESSORIES CO., LTD. With product testing equipment is complete, with Nano electron accelerator, injection moulding machine, rubber molding machine and other production and manufacturing equipment. Also it has high pressure screening test center, fully meet the needs of product inspection and testing.

Rubber is known to have "elastic memory" properties, like a spring. Cold shrinkage technology, also known as pre-expansion technology, the elastic rubber in the elastic range of pre-support, set into the plastic support strip to be fixed. When installing, as long as the support strip is removed, the elastic body rapidly shrinks and tightens on the cable body. The cold shrinkage products manufactured by HUAYI CABLE ACCESSORIES CO., LTD. are all bonded with special sealing adhesive to make the overall sealing and avoid operation accidents caused by atmospheric environment. The silicone rubber used for raw materials has excellent insulation and high resilience, and will not cause electrical breakdown due to the breathing action of the cable during operation after installation. The products are widely used in electric power industry, communication industry, military industry, metallurgy, coal mining, petrochemical industry and other fields.

The Cold Shrinkable Cable Accessories with features of full shrinkage automatic reset technology, installation without special tools, construction and installation is simple and quick; No open flame, no heating, safe and reliable; The cable body has persistent radial pressure, good sealing and waterproof, to ensure long-term reliable operation.

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 product is waterproof, stress control, shielding, insulation in one, can be used in a variety of harsh environmental conditions for a long time. Widely used in Electric Power Industry, Petroleum Industry, Chemical Industry, Metallurgy, Railway, Port, Construction and other fields.

Production line

We specialize in power cable accessories, electric power facilities of bus-bar heat shrinkable tube, special-shaped heat-shrinkable products and silicone rubber safety shield electric contact,etc..We also has electron accelerator production equipment which can undertake external irradiation ability. Products are tested qualified by the national electric power industry electrical equipment quality inspection and test center and met the requirements of GB/T12706 standard.

HUAYI CABLE ACCESSORIES CO., LTD. also own an Electron Accelerator Irradiation Center. The processing of electron accelerator radiation (hereinafter referred to as irradiation) refers to the use of high energy electron accelerator, radiation to the surface or internal processing, physical or chemical reaction in the processing object, so as to change some properties of the object processing technology. Polymer materials radiation crosslinking is form chemical bonds between polymer long chain or onlookers strong physical combining site, so that the physical properties, chemical properties of polymer for improvement.

production equipment

Radiation crosslinking of the main products are heat shrinkable materials, wire and cable insulation materials and polyethylene foam. Polymer materials radiation crosslinking, the line into the reticular structure, the corresponding changes in its performance. From can melt into not melting, high temperature resistance and high temperature intensity has obvious increase; Form new connections between molecular keys, to prevent the molecular relative slip, enhance rigidity; So that after irradiation processing, the product have characteristics of good flame retardant, cold resistant, heat resistant, radiation resistant, resistant to bad environment etc., widely used in electricity, electronics, petroleum, automotive, and other industrial fields.

Our company now has more than one irradiation accelerator, has a full set of production and testing equipment, has large quantities of irradiation conditions and leading irradiation technology advantage, provide irradiation crosslinking wire and cable, heat shrinkable materials irradiation processing business.

Irradiation processing technology collection of electronic technology, high energy nuclear physics technology, vacuum technology, computer technology, radiation chemical technology and wire and cable manufacturing technology at an organic whole. High-energy electron beam produced by electron accelerator, the role within the polymer, the polymer molecular structure is changed, the original linear macromolecules into insoluble don't melt three-dimensional network structure. The main characteristics of its products are: 

·Good heat resistance: Such as to allow for a long time after irradiation crosslinking polyethylene material working temperature can be raised from 60-70 ℃ to 90-150 ℃, short circuit temperature from 160 ℃ to 250 ℃.
·Improve the carrying capacity of cable: The conductor cross section carrying capacity increases about 20%-50%. 

·With excellent insulation properties and electrical performance. 

·High mechanical strength, aging resistance and chemical stability and good environmental stress cracking resistance. Improve the flame retardant performance.

·High safety and long performance life which can be up to 40 years.
