Copper core crosslinked polyethylene insulation armored power cable

Technical Field

The utility model belongs to the technical field of the cable, especially, relate to an insulating armor power cable of copper core crosslinked polyethylene.

Background

Cables are generally made up of several wires or groups of wires, made up of one or more conductors insulated from each other and an outer insulating sheath, which carries power or information from one place to another. The cable has the characteristics of internal electrification and external insulation. The cables used for connecting the circuits and the electric appliances include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables and the like.

However, the existing cable is unreasonable in structural design, and the overall structural stability is not good enough, so that the existing cable is easy to be damaged along with the increase of the service time, and the overall safety performance is affected; inside cable core laminates each other, and when the conflagration breaing out, the cable can not bear high temperature, causes the damage of cable core insulating layer, and then appears the short circuit phenomenon between the cable core, and the fire prevention insulating filler that space department between the cable core of laminating design was filled is not enough even, leads to local area not to have the fire prevention insulating filler, has the potential safety hazard, and once the conflagration takes place, the cable is cut off, will lead to the fact very big difficulty to rescue and flee for one's life.

Therefore, the existing requirements are not met, and the problem of solving the problem is solved by providing the insulated cable with fireproof and fire-resistant functions.

SUMMERY OF THE UTILITY MODEL

The utility model provides an insulating armor power cable of copper core crosslinked polyethylene.

The utility model discloses a following technical scheme realizes: including conductive core, conductive core outside parcel in proper order sets up sinle silk insulating layer, sinle silk shielding layer and anti ageing layer and constitutes independent sinle silk, wherein, independent sinle silk has three, three independent sinle silk sets up in wear-resisting interior sleeve pipe, and is the setting of delta font, sets up a enhancement sinle silk between three independent sinle silks it has insulating material to fill in the wear-resisting interior sleeve pipe, and insulating material wraps up three conductive core, enhancement sinle silk as an organic whole to it is fixed to stereotype, wear-resisting interior sleeve pipe outside from inside to outside sets gradually keeps warm-water insulation fire barrier, fire-retardant layer, armor, flame retardant coating and insulating wear-resisting skin.

The utility model has the advantages that:

1. the utility model discloses an at the inside packing insulating material of insulated cable main part, insulating material wraps up three conductive core as an organic whole to the design is fixed, the inside friction of avoiding the cable that can be better, the installation stability can of cable has obtained better guarantee, and the working property is also more stable, and the stable form of having solved current cable overall structure is not good enough, appears damaged along with the increase of live time easily, influences the problem of whole security performance.

2. The utility model discloses a be provided with the armor, the inside insulated cable main part of protection that can be better avoids because the damage that the long-time friction that uses produced to and be bitten bad by the toy, through being provided with the insulating cover of multilayer, the insulating properties of guarantee cable that can be better, safer, overall structure's factor of safety is higher.

3. The utility model discloses a set up the enhancement line and improved cable bulk strength, shielding layer anti-electromagnetic interference, fire-retardant layer plays the effect of realizing fire-retardant and protection, has effectively improved the quality and the life of cable.
