Cable accessories mainly used for high voltage transmission distribution of the electric power industry is the traditional cable accessories upgrade products, as an important component of its various imported silicone rubber and high tear pre prepared with high elasticity, the manufacturer, on-site installation without fire, thus saving time and force, stable performance, less affected by human factors, which can greatly improve the safety and reliability of cable accessories.　

The cold shrinkable cable accessories for cold shrinkable tube manufacturers have the following characteristics:　

Cable accessories, cable accessories, products and expansion machine, cable branch box, cable accessories processing, and power cable accessories, and pipe manufacturers, cold 　

The most easily damaged part of the general cold shrink cable accessories is the intermediate connection head of the cable and the terminal head and its vicinity, especially the intermediate connection head　

Cold shrink cable accessories metal shielding grounding caused by imperfect, in general there are two XLPE cable grounding, and grounding resistance should be less than the specified value, so as to effectively protect the cable, if the grounding resistance value exceed the standard, when the cable and connector received voltage, will produce better induction voltage thus, part of the insulation breakdown causes aging. 　

As a popular cable accessory in recent years, the amount of cold shrink cable accessories is increasing. With the increasing number of manufacturers producing cold shrinkable cable accessories, the brands of cold shrink cable accessories are also increasing. 　

The products of cold - shrinkable cable accessories are introduced in detail.　

With the development of distribution network's cable process, when the independent load distribution of small capacity is centralized, cable branching box can be used to connect multiple branches of cables. As long as any trigger acts, the linkage will make the three phases of load switch automatically open at the same time. The cable branch box can meet the requirements of various normal and failure operation protection of the distribution system.
