Fireproof high-temperature-resistant power cable

Abstract

The invention discloses a fireproof high-temperature-resistant power cable with excellent fireproof performance. The center of the fireproof high-temperature-resistant power cable is provided with an alloy copper conductor, a silicon carbide insulation layer is extruded outside the alloy copper conductor, and an inner jacket and an outer jacket are sequentially arranged outside the silicon carbide insulation layer. The inner jacket is a welding copper pipe, and the outer jacket is co-extruded by a PP (Propene Polymer) copolymer.

Description

[0001] technical field

[0002] The invention relates to a cable, in particular to a fireproof and high temperature resistant power cable. Background technique

[0003] In social life, fire is one of the disasters that threaten public safety and endanger people's lives and property. Today, fire is a common catastrophic problem faced by people all over the world. It has caused many serious losses of life and property to human society. With the development of social productive forces, social wealth is increasing day by day, the general trend of fire loss rising and fire hazard scope expanding is an objective law. However, ordinary power cables have low temperature resistance and poor fire performance, which brings a lot of inconvenience to fire rescue work. Contents of the invention

[0004] The object of the present invention is to provide a power cable with excellent fireproof performance aiming at the deficiencies in the prior art.

[0005] The fire-proof and high-tem...

Embodiment Construction

[0014] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. are intended only and not to limit the scope of the invention.

[0015] Such as figure 1 , a fire-proof and high-temperature-resistant power cable of the present invention, wherein the center of the cable is an alloy copper conductor 1, and the alloy copper conductor 1 is extruded with a silicon carbide insulating layer 2, and the silicon carbide insulating layer 2 is sequentially provided with a welded copper tube inner sheath Sheath 3 and PP copolymer extruded outer sheath 4.

[0016] The maximum service temperature of silicon carbide fiber is 1200℃, its heat resistance and oxidation resistance are better than carbon fiber, its strength is 1960-4410MPa, its strength retention rate is over 80% at the maximum service temperature, and its modulus is 176.4-294GPa. Chemical stability is also good. Silicon carbide fibers are mainly used as high te...
