Elastic rubber materials are known to have "elastic memory" properties, like springs. Cold shrinkage technology is also known as pre-expansion technology, that is, the use of mechanical means to shape the rubber parts in its elastic range in advance, and then set into the plastic core to be fixed.
The Heat Shrinkable Cable Accessories is one of the important parts in the transmission system. The quality of Heat Shrinkable Cable Accessories is related to the safe operation of power grid. Once the Heat Shrinkable Cable Accessories fails, it will cause huge loss. Therefore, the installation and acceptance of Heat Shrinkable Cable Accessories is particularly important.
Heat shrinkable tube is composed of radiation polymerization, contraction tightly wrapped in the cable joint after heating, so as to achieve insulation, sealing and protection. It is widely used for waterproof electronic equipment, sealing of cable branches, corrosion protection of metal pipes and prevention of loosening and shedding caused by loose polymer chains.
High voltage cable termination installed in the stress ball capacitor cone or capacitor cake to ease the intensity of the power line has achieved successful experience, as is known to all, without the above control of electric field stress device, will be close to the grounding shield end, free discharge, thus shortening the life of the cable termination.
The new Specification, Standard, Main Performance and a part of Type tests for 110kV Composite Cable Termination. Compared with the traditional porcelain tubing, the composite tubing has many advantages, It is the best substitute for porcelain covers and has gradually been accepted all over the world.
Installation must be operated by specially trained personnel, they must be familiar with the product structure,the installation process and the important dimension. When necessary, the installation time, project name and number to do detailed records, and signed by the installation personnel confirmation, document for future reference.
