Tensile fireproof waterproof flame-retardant cable

Abstract

The invention relates to the technical field of cables, in particular to a tensile fireproof waterproof flame-retardant cable, comprising an outer sheath, a first reinforcing layer, a second reinforcing layer, a waterproof layer, a first fireproof layer and a second fireproof layer which are arranged sequentially from outside to inside. First reinforcing ribs which are T-shaped ribs are arranged on the inner sidewall of the first reinforcing layer at equal intervals; a first clamp groove that is a T-shaped groove is arranged in the sidewall of the first reinforcing layer between every two adjacent first reinforcing ribs; the second reinforcing layer is arranged on the side, far away from the outer sheath, of the first reinforcing layer; second reinforcing ribs which are T-shaped ribs are arranged on the outer wall of the second reinforcing layer at equal intervals; the second reinforcing ribs are clamped to the first clamp grooves; the outer wall of the second reinforcing layer is provided with second clamp grooves between the second reinforcing ribs, and the second clamp grooves which are T-shaped grooves are clamped to the first reinforcing ribs.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a tensile type fireproof, waterproof and flame-retardant cable. Background technique [0002] In today's society, with the rapid development of the economy, the amount of wires and cables is increasing rapidly, and the amount of wires and cables suitable for some special occasions is also increasing sharply, such as ships, oil production platforms, petrochemical enterprises, large power stations, etc. The demand for cables is very important for them to maintain a certain stable operation in the event of fire, flood, etc. As the information transmission carrier, the fireproof, waterproof and tensile properties of cables have gradually become a hot field of research by engineers from various countries, but the existing cables are in application In the process, it cannot be effectively fire-resistant and flame-retardant, and its tensile performance is not good, which is unfavorable f...
