specific Embodiment approach

[0014] The content of the present invention will be described below in conjunction with specific embodiments.

[0015] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a high temperature resistant flame retardant power cable proposed by the present invention.

[0016] A high temperature resistant and flame retardant power cable, comprising: a cable core located in the middle, a total wrapping layer 5, an outer refractory material layer 6, an armor layer 7 and an outer sheath 8 which are sequentially coated on the outside of the cable core.

[0017] The overall wrapping layer 5 can be formed by wrapping the outer periphery of the cable core with a water-blocking tape, which can prevent water molecules from penetrating into the cable core while maintaining the regularity of the cable core, thereby improving the resistance of the power cable. water performance.

[0018] The outer refractory material layer 6 can be formed by covering the outer periphe...

Abstract

The invention relates to a high temperature resistant flame retardant power cable, comprising a cable core, a total wrapping layer, an outer refractory material layer, an armor layer and an outer sheath; the cable core includes a flame retardant sleeve and four wires; the flame retardant sleeve It includes four flame retardant parts, which are connected end to end in sequence, and an outer elastic part is arranged between any two adjacent flame retardant parts, and the outer elastic part has an outer arc surface and two inner arc surfaces , the outer arc surfaces of the outer elastic parts cooperate with each other so that the cable core has a circular cross-section, and the inner arc surfaces of the outer elastic parts respectively abut against the outer arc surfaces of the two flame retardant parts; the wires abut against the On the inner arc surface of the flame retardant, the central connection line of the four wires is a square, and an inner elastic piece is arranged between the four wires, and the inner elastic piece is circumscribed with the wire, and there is an inner elastic piece between the four wires and the inner elastic piece. Tensile core, the tensile core is wrapped around the inner elastic. The invention has excellent high temperature resistance and flame retardancy, large carrying capacity and high safety.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a high-temperature-resistant and flame-retardant power cable. Background technique [0002] Due to the continuous and rapid development of my country's economy, the power supply is very tight, which has triggered an upsurge in investment and construction of power infrastructure, especially high-voltage power cables are widely used in urban power grids. As the power transmission capacity of cables continues to increase, the requirements for the safety performance of cables are also getting higher and higher. Traditional power cables have weak high temperature resistance and flame retardancy, and poor compression resistance, which affects normal power communication. Contents of the invention [0003] The present invention just aims at the deficiencies of the prior art, and provides a high-temperature-resistant and flame-retardant power cable. [0004] In order to solve the a...
