The structure of the zipper heat shrink tube is very simple and mainly consists of three parts: a repair piece, a zipper buckle and a waterproof hot melt adhesive piece. The zipper buckle is used to lock the repair piece, the waterproof hot melt adhesive sheet prevents water vapor from intruding, and the repair piece is used for repair. Zippered heat shrink tubing is also very versatile and can quickly repair damaged cables in an emergency.

1. Used to repair damaged outer sheaths of various cables: Zipper-type heat shrinkable tubes can simply and quickly seal and insulate the damaged outer sheaths of 1-35KV cables. It can be used with both high and low voltages, no need to cut off the power, and is used for emergency repairs. The construction is simple, the size selection range is wide, and it is suitable for various occasions.

2. Used for the protection of low-voltage cable head branches: secondary sealing of cable head branches, used in tunnel lighting line systems and urban street light wiring systems.

3. Repair of offshore platforms and marine cables can overcome harsh environments: the main material of the zipper heat shrinkable tube is irradiation cross-linked polyethylene sheathing material, which has good acid, alkali and salt corrosion resistance and excellent mechanical properties. It is used in marine, Offshore platforms and container terminals are used.

4. Outer sheath for intermediate connections of low-voltage cables: When the underground cable trench space is small, this product can be used as an outer sheath for intermediate connections of cables. Its "zipper type" feature facilitates construction operations and reduces earthwork excavation. dig.

5. Used for underground waterproof protection of cables: The underground installation of power and communication cables is a trend in urban construction. This product is currently widely used for the pipe protection of electric power underground projects.

6. The zipper setting concept can quickly repair the cable sheathing layer, and can easily and quickly seal the damaged cable to achieve insulation protection.

7. The inner wall is equipped with hot melt adhesive, which has good waterproof, insulating, moisture-proof, anti-corrosion and sealing properties, and is insulated and waterproof.

8. It is widely used to repair damaged outer sheaths of high and low voltage power cables, communication cables, communication optical cables and other cables.
