Low smoke zero halogen industrial cable

Abstract

The invention discloses a low smoke zero halogen industrial cable. The cable comprises a shielding layer, wherein a low smoke zero halogen wrapping band is arranged on the surface of the shielding layer; the low smoke zero halogen wrapping band adopts a dual-layer structure, and a gridding cloth structural layer is arranged between the layers; the surface of the low smoke zero halogen wrapping band is coated with a waterproof layer; the waterproof layer is adhered to the low smoke zero halogen wrapping band; an insulating layer is arranged in the shielding layer; a built-in insulator is arranged between the shielding layer and the insulating layer; a cable core, more than one thermal insulating conductor and a tin-plated soft conductor are arranged in the insulating layer; and the cable core, the thermal insulating conductors and the tin-plated soft conductor are tightly connected. The low smoke zero halogen industrial cable provided by the invention is compact in structure, good in waterproof performance, and capable of preventing rain water from entering the cable core to affect the use performance; and meanwhile, the cable can bear a certain mechanical external force, and is capable of greatly improving the insulating performance, convenient to use, safe, and reliable.

Description

technical field [0001] The invention relates to a cable, in particular to a low-smoke and halogen-free industrial cable. Background technique [0002] As a carrier of electric energy transmission and distribution, power cables are widely used in various industries. Due to the improper use of man-made or the influence of external factors such as lightning strikes and earthquakes, cable fires occur from time to time. After a general cable fire, it will Toxic smoke is produced. If too much smoke is inhaled, it is likely to cause death due to suffocation, and the visibility of the smoke produced by toxic smoke is low. Once a crisis occurs, it is difficult to identify the direction and escape from the fire scene. And with the development of society, the power consumption also increases, the current carrying capacity of the cable is required to be larger and larger, the cross section of the conductive core of the cable is constantly increasing, the weight per unit length of the ca...

[0002] As a carrier of electric energy transmission and distribution, power cables are widely used in various industries. Due to the improper use of man-made or the influence of external factors such as lightning strikes and earthquakes, cable fires occur from time to time. After a general cable fire, it will Toxic smog is produced. If too much smog is inhaled, it is likely to cause death due to suffocation, and the visibility of the smog produced by toxic smog is low. Once a crisis occurs, it is difficult to identify the direction and escape from the fire scene

And with the development of society, the power consumption also increases, the current carrying capacity of the cable is required to be larger and larger, the cross section of the conductive core of the cable is constantly increasing, the weight per unit length of the cable is also increasing, and the laying amount is large. , it is also necessary to consider the problem of water resistance. If the water resistance effect is poor, it is easy for water to enter the cable core and cause accidents.
