Problems solved by technology

If the cable material does not meet the requirements, it will cause the cable to be brittle and even decompose the cable sheath. All of these situations will directly increase the loss of the cable system, and at the same time, the risk of cable short circuit will also increase. In the medium and long term, fire or personnel The possibility of injury is also higher, so there is a need for a flame-retardant insulated cable that can adapt to multiple temperatures to solve the above problems

Abstract

The invention discloses a flame-retardant insulated power cable, which comprises a cable body, wherein the outer side of the cable body is provided with a conductor outer sleeve, the inner side of theconductor outer sleeve is provided with a reinforcing layer, the inner side of the reinforcing layer is provided with a conductor shielding intermediate glue layer, the inner side of the conductor shielding intermediate glue layer is provided with a conductor shielding layer, the inner side of the conductor shielding layer is provided with a halogen-free insulating flame-retardant layer, and conductors are arranged inside the halogen-free insulating flame-retardant layer. The flame-retardant insulated power cable has the advantages of high low-temperature resistance and good high-temperatureresistance; the tensile strength of the product is high; the product has high flame retardance and insulation performance, and is more suitable for practical life; the surface integrity of a filler isimproved by performing secondary coating on the filler, and the waterproof performance of the filler is improved; and the manufacturing method is simple, and the experiment operation can be performedwithout consuming too much energy.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flame-retardant insulated power cable. Background technique [0002] Cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts; one or more insulated cores, and their respective possible coatings. Protective layer and outer sheath, the cable may also have additional uninsulated conductors. [0003] With the development of society, cables are used in many corners of real life, and the performance requirements for cable products are getting higher and higher. Good heat resistance, humidity resistance, low temperature resistance, chemical corrosion resistance, insulation and halogen-free resistance Flammable perfor...
