Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0014] refer to figure 1 , the specific embodiment adopts the following technical scheme: a silica cable, including a sheath 4, an outer conductor 3, an inner conductor 1 and an insulating layer 2, wherein the sheath 4 is wrapped in the outer layer of the outer conductor 3 The outer conductor 3 is wrapped in the outer layer of the insulating layer 2; the inner conductor 1 is arranged in the insulating layer 2.

[0015] It should be noted that the inner conductor 3 is high-purity oxygen-free copper or other conductors.

[0016] It should be noted that the insulating layer 2 is silicon dioxide with high foaming and low loss.

[0017] It is worth noting that the silica concentration exceeds 80%.

[0018] It should be noted that the outer conductor...

Abstract

The invention discloses a silicon dioxide cable which includes a sheath, an outer conductor, an inner conductor and an insulating layer. The silicon dioxide cable is characterized in that the sheath wraps the outer conductor, the outer conductor wraps the insulating layer, and the inner conductor is arranged inside the insulating layer. The silicon dioxide cable provided by the invention is good in fire resistant performance, and is resistant to high temperature, low in cost and high in safety.

Description

technical field [0001] The invention relates to a silica cable. Background technique [0002] Silica cables are widely used in high-rise buildings, underground railways, underground streets, large power stations, important industrial and mining enterprises and other places related to fire safety and fire rescue, such as power supply lines and control lines of emergency facilities such as fire-fighting equipment and emergency guide lights. Although the existing mineral insulated cables can still maintain normal power supply for a period of time after a fire, there are problems of high price, complicated process and difficult construction Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a silica cable with good fire resistance, high temperature resistance, low cost and high safety. [0004] In order to achieve the above object, the present invention is achieved through the following technical...
