The material of cold shrinkable cable accessories is mainly silicone rubber, and the material of heat shrinkable cable accessories is mainly PE, from the point of use, cold shrink cable accessories are more convenient, heat shrinkable cable accessories need heating installation, more complex than cold shrinkable cable accessories.
heat shrink cable accessories and cables are integrated, after cooling can obtain high mechanical strength, can resist quite high pressure, and can be sealed waterproof; In addition, an iron shell protective layer is designed and installed at the underground connection interface to further increase its mechanical strength, wear resistance and water resistance.
There are many scientific research achievements in the temperature monitoring of wire and cable joints in the world, which are distinguished by data signal collection methods, and the key is electronic signal measurement and optical signal temperature measurement.
A wide variety of cable accessories, each cable accessories have different characteristics and different types of product characteristics and limitations, cable accessories between the varieties can not replace each other. In general, outdoor refers to open-air wire and cable accessories, while indoor refers to the connection between cables and electrical equipment.
The heat-shrink tube is a new kind of anti-corrosion material for steel pipe weld with good performance and easy operation. It is composed of double layer material of substrate and hot-melt adhesive layer. The base material is a plastic sleeve formed by polyethylene raw material base, radiation crosslinking and stretching. Hot melt adhesive is a special adhesive, solid at room temperature, heated in a molten state can flow, can be coated on the substrate, metal and plastic have good adhesion.
Heat shrinkable cable Termination kit and Joint kit Applicable to voltage classes of 1, 6/10, 8.7/15, 12/20, 21/35, 26/36kV, Indoor, outdoor termination and straight through joint of single core, two core, three core, four core and five core power cables with a nominal cross-section of 25-500mm2 of crosslinked polyethylene insulation
