High-pressure heat-shrinkable tubes with high resistance of 1.0KV or more are usually called high-pressure heat shrinkable tubing. The general pressure-resistance grade of ordinary heat-shrinkable tube is 0.6kv. The common pressure-resistance grade of high-pressure heat-shrinkable pipes is 1.0KV, 10KV, 35KV, etc. The high-pressure heat-shrinkable pipes of our company are qualified by the testing center of electrical equipment quality of the Ministry of Electric Power Industry, and meet the requirements of GB8114-95 standard. The main color of high-pressure heat-shrinkable tube is double-wall heat-shrinkable tube: red, yellow, green, blue and black. The insulation protection for busbar of high and low voltage switchgear in substation can make the structure of switchgear compact (shorten the distance between phases) and prevent accidental short circuit accidents.
High temperature shrinkable tubes have the advantages of high temperature resistance, high mechanical strength and good chemical resistance. They are also widely used in cable insulation protection, insulation treatment or stress relief at the end or connection, wire processing coating and insulation protection, solder joint protection, coating of electronic components, insulation protection of resistors and capacitors, anti-rust, anti-corrosion treatment of metal products, marking or marking of wires, etc.
Thermal shrinkage pipes can also be divided into 125, 135, 150, 175, 200, 260 and medical heat shrinkage pipes according to the grade of temperature and the environment in which they are used. Moreover, the synthesis of special high-temperature resistant materials also determines that high-temperature heat shrinkage pipes have many points which are difficult to replace by similar materials. In general, the heat-shrinkable pipes above 125 C, such as 135, 150, 175, 200, 260 and medical heat-shrinkable pipes, are collectively referred to as heat-resistant heat-shrinkable pipes.
Yellow green heat shrinkable tube is a special heat-shrinkable tube. The yellow-green heat-shrinkable tube is made of high-quality yellow and green polyolefin heat-shrinkable tube material through special processing. Moreover, after forming the yellow-green belt heat-shrinkable tube, the product will have the advantages of softness, flame retardancy, bright color persistence and stable performance after irradiation cross-linking and continuous expansion by an electronic accelerator.
Its characteristics are that the range of use is between - 55 ~125 C, the initial shrinkage temperature is 70 C, and the complete shrinkage temperature is 115 C. The most important feature is that it is easy to use, and can shrink by heating with oven and hot air gun. Yellow-green heat shrinkable pipes are usually used for connection of yellow-green wires, ground wires in cables or other special lines, and pipe marking.
