Description

Technical Field

[0001] The utility model relates to the technical field of electric wires and cables, in particular to a flame-retardant electric wire. Background Art

[0002] At present, the outer casing of electrical devices or household appliances is not electrified during normal operation, but may be electrified during a fault, making people's lives and property safety uncertain. People are paying more and more attention to wires, and my country's urban construction continues to extend to high-rise and underground areas. A large number of high-rise buildings, subways, tunnels, power stations, ships, etc. have increasing requirements for wires. Most of these places are densely populated, and it is difficult for people to evacuate in the event of a fire, so these places have higher requirements for the wires used.

[0003] Existing electrical wires usually have a flame retardant layer on the outer layer, but do not have good flame retardancy. After working for a long time, as the temperature of one battery cell gradually rises and burns, it is easy to affect other battery cells, thus easily causing a fire. Utility Model Content

[0004] The utility model aims to solve the problem that the existing electric wires have poor flame retardancy and are prone to cause fires, and to provide a flame retardant electric wire.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model provides a flame retardant electric wire, comprising

[0007] A plurality of core components, the core components comprising

[0008] A wire core body, wherein a first flame retardant layer and a first insulating layer are sequentially arranged on the outer side of the wire core body;

[0009] A second flame retardant layer and a second insulating layer are sequentially arranged on the outer sides of the plurality of wire core components, and a filling layer is arranged between the second flame retardant layer and the wire core components;

[0010] A partition sheet is provided between adjacent wire core components, and the partition sheet is located in the filling layer.

[0011] Furthermore, a heat insulation layer is provided between the wire core body and the first flame retardant layer.

[0012] Furthermore, a plurality of anti-slip strips are provided on the outer side wall of the second insulating layer.

[0013] Furthermore, a plurality of cutting grooves are evenly spaced apart on the outer side wall of the second insulating layer along its extension direction.

[0014] Furthermore, the filling layer is a mineral layer.

[0015] The beneficial effects of the utility model are:

[0016] 1. By setting a first flame retardant layer outside the wire core assembly, it can prevent external fire from burning the inside. At the same time, a second flame retardant layer is also set on the wire core body and a partition piece is set to separate the wire core body, which can better prevent the wire core body from heating up and burning due to long-term work, causing other wire core bodies to catch fire, thereby better preventing fire.

[0017] 2. By providing a cutting groove on the outer side wall of the second insulating layer, it is convenient to cut the flame-retardant wire with a blade using the cutting groove as a starting point, thereby improving the overall practicality. BRIEF DESCRIPTION OF THE DRAWINGS
