HTV) is formed of a silicone material, but is integrally molded when the insulator lamp 250 is injected.

In other words, PVC wire or EPDM natural rubber is mainly used for the material of the existing insulator cap 250, but when used for a long time, the water repellency decreases due to material limitations, resulting in various insulation accidents.This problem can be solved by water repellency and tracking resistance. It can be solved by applying it with excellent and eco-friendly high-temperature curing (HTV) silicone material.

In addition, since the outer covering of the lead wire 320 is integrally molded with the cover 310, it is possible to prevent the formation of a gap in the fastening part, and to prevent the penetration of moisture such as snow or rain.

And as the lead wire is manufactured as an integral type, it is possible to shorten the work process by improving the existing two-point connection method (separate lead wire to the line and upper bracket, respectively) to a one-point connection method that connects only to the line side.
