With the rapid development of modern industry, more and more industries use automatic equipment to replace manual operation, especially in a manufacturing industry, high-temperature industry and so on. What maintains the normal operation of these equipment is the power transmitted through cables. Secondly, there are various pipelines and oil pipes on some equipment. In some severe working conditions, these need to be protected. Only by protecting them from damage can we ensure the normal operation of production equipment. High temperature resistant fire sleeve is made of alkali free glass fiber coated with silicone rubber. Strict manufacturing process can ensure the quality of protective sleeve. Secondly, according to different applications, we also have a variety of structural forms of protective sleeves. GWH fire sleeve has good protective effect under the specified service conditions. It can be disassembled and used repeatedly without affecting the protective effect. With such a powerful protective sleeve, all kinds of cables, oil pipes and hoses can easily work normally in high temperature environment. There are many specifications and models of Beijing Great Pack fire sleeve, which can be applied to the protection of different pipeline equipment.
