Silicone rubber Fiberglass Casing, also known as fire-resistant casing, high-temperature casing, high purity alkali-free glass fiber prepared into the tube, and then in the tube outside the wall coating silicone through vulcanization treatment. After vulcanization can be used in the temperature range of 65 °c C-260 °c for a long time and maintain its soft and elastic properties. Generally suitable for the protection of shorter or more straight pipelines, cable protection, automotive wiring harness, generator set commonly used, after the installation of solid, not easy to disassemble,
sealing, insulation, heat insulation, moistureproof effect is better.

Composite insulating casing, used as insulating medium for oil or gas, is usually made into a transformer casing or circuit breaker casing, which is usually rated at 35,000 volts below. The inner cavity of the composite insulated casing conductor and the porcelain suite is filled with transformer oil and plays a radial insulating role. When the voltage exceeds 35,000 volts, the conductor is sheathed with an insulating tube or a package cable to enhance insulation. The conductor structure of composite insulated casing has two kinds of cable-type and guide-Rod. The cable-type use of
the transformer’s lead cables directly through the casing, easy installation.
