Product Description

Introduction of 7KV fiberglass casing:

The 7KV glass fiber sleeve is made of high-purity alkali-free glass fiber weaved into a tube, and then coated with organic silica gel on the outer wall of the tube and then vulcanized. After vulcanization, it can be used for a long time in the temperature range of -65°C-260°C and maintain its soft and elastic properties.

7KV Fiberglass Sleeve


Features:

1. Safety and environmental protection, protect the health of workers

The alkali-free glass fiber in the 7KV glass fiber casing has strong tensile strength, will not be wrinkled and broken, is resistant to vulcanization, is smoke-free, halogen-free, non-toxic, pure oxygen, non-combustible, and has good insulation characteristics. After the organic silicone is cured, it will be strengthened. The safety and environmental protection performance effectively protects the human health of workers and reduces the incidence of occupational diseases. Unlike other products, which are extremely harmful to humans and the environment.

2. Thermal insulation, energy saving and consumption reduction, radiation resistance

In high-temperature workshops, many pipes, valves or equipment have very high internal temperatures. If they are not covered with protective materials, it is easy to cause burns or heat loss. Especially the 7KV glass fiber casing has better thermal stability than other polymer materials, as well as radiation resistance and thermal insulation, preventing accidents, reducing energy consumption, and preventing the heat of the medium in the pipeline from being directly transferred to the surroundings. The environment makes the temperature of the workshop too high, saving the cost of cooling.


Application range of 7KV glass fiber casing:

Wire harness, hot runner, steel, smelting, shipbuilding and chemical industry and other high temperature areas, heating area cables, fluid pipelines, rolling mill cables, oil pipes, sawing edge cables, generator sets, electrical voltage equipment, oxygen sensors, large buildings , Hydraulic system, automobile wiring harness and exhaust pipe, etc.

FAQ:

Q: Is it high temperature resistant? Will cracks occur after high temperature resistance?

A: The 7KV glass fiber casing is woven with extremely high temperature resistant glass fiber, and the surface silica gel is added with special materials such as appropriate flame retardants to make it have excellent temperature resistance, long-term continuous use temperature range, -10℃~200℃, with or without cracks and cracks.

Q: Your bending and twists will reduce the electrical insulation?

A: Our conventional 7KV glass fiber casing body has high electrical insulation, and has good heat resistance, corrosion resistance and heat dissipation. Because of its excellent flexibility and elasticity, it is at minus 60°C. The low temperature can also maintain its flexibility, and its film is strong and resistant to tortuous, although it is twisted, it will not detract from its electrical insulation.

Q: Are your products flame retardant?

A: Our 7KV fiberglass sleeving products are flame-retardant and meet the American UL testing standards.
