Cold Shrink Cable Accessory Finger Cots

Cable finger sleeves, generally referred to as finger sleeves or gloves, are also a type of cable accessories. They are mainly used for insulation and sealing at the bifurcation of power cables and are generally used in conjunction with cable terminals.

Cable finger sleeves can be divided into two types according to the material: heat shrink cable finger sleeves and Cold Shrink Cable Accessories, referred to as heat shrink finger sleeves and cold shrink finger sleeves. Heat shrink finger sleeves are black in color and made of the same material as heat shrink cable accessories. They are made of PE and have hot melt adhesive on the inner wall of the finger sleeve. When used, they are put on the branch of the multi-core cable core. When heated, they shrink. The hot melt adhesive on the inner wall will tightly adhere the cable, thereby playing a role in waterproof and moisture-proof sealing protection. The radiation cross-linked polyolefin material on the outer layer can play a role in electrical insulation protection.

After talking about heat shrink finger sleeves, let's talk about cold shrink finger sleeves. The cold shrink finger sleeve is gray in appearance and feels elastic. Like Cold Shrink Cable Accessories, it is made of silicone rubber, so its usage method is the same as Cold Shrink Cable Accessories. When using it, put it on the corresponding covered object, slowly pull out the white plastic support strip in the finger sleeve, it will naturally shrink and firmly cover the covered object, playing the role of waterproof, moisture-proof and sealing.

Cable finger sleeves can be divided into two-core finger sleeves, three-core finger sleeves, four-core finger sleeves and five-core finger sleeves according to the number of cores.

Cable finger sleeves can also be divided into three types according to the voltage resistance level: 1kv cable finger sleeves, 10kv cable finger sleeves and 35kv cable finger sleeves, among which 10kv cable finger sleeves and 35kv cable finger sleeves only have three-core finger sleeves.

Of course, in addition to the difference in material and voltage level, the applicable square number, inner diameter before and after shrinkage, wall thickness, length, etc. of each finger sleeve are different.
