How to choose high temperature resistant casing?

The commonly used high-temperature casings are mainly glass fiber casings woven with high-loft glass fibers and coated with imported high-quality silicone rubber, which can prevent splashes of molten iron, molten copper, molten aluminum, etc., and It is not damaged by high temperature and flame, ensuring the overall strength of the casing during installation and the stability coefficient under high temperature environment.

　　 When choosing a high-temperature casing, it is best to select a sample first and cut it to check the color of the glass fiber inside. Conventional glass fiber is white, and some of them are milky white or light yellow. It can be judged whether it is qualified according to its color and outer layer of silica gel. In order to save costs, some manufacturers will add other substances to the glass fiber. Such products will greatly affect the insulation effect and service life of the casing.

Qualified high-temperature casing, because its surface uses imported high-quality silicone rubber, it has the characteristics of dustproof, waterproof and easy to manage. Its normal working temperature is 260℃, which is suitable for most working conditions. It can withstand 5-10 minutes at a temperature of 1090°C, adapting to a short-term high temperature environment, and at a high temperature of 1650°C, it can withstand 15-30 seconds, prolonging the discovery and handling process in emergencies.

As a new type of environmentally friendly material, high temperature resistant fireproof casing is a technical product for the purpose of preventing and controlling environmental pollution, improving the ecological environment, and protecting natural resources. It is developed with good high temperature resistant insulation, flame retardant and fireproof characteristics, and it is woven with alkali-free glass fiber. The tube is coated with silicone resin and processed at high temperature. Both glass fiber and silicone resin are green and pollution-free raw materials, which are harmless to the human body. It is applied to all cables and pipes that need protection in high temperature areas.

　　 It is best to choose a manufacturer with quality assurance when purchasing high temperature bushings, such as Jie brand bushings, which are more reliable in terms of product performance. Moreover, the company has been in business for a long time and the brand has a strong influence. If the people who have bought the product say yes, then they can choose.
