Abstract
The utility model discloses a cross-linked polyethylene insulation safe cleaning power cable, comprising a plurality of conductors. The outside of each conductor is wrapped with an insulating layer and a lapping layer, the lapping layer is formed by bonding a layer of water-blocking tape between two layers of fire-resistant mica tapes, and three groups of glyph arranged filling ropes are arranged between the lapping layer and the insulating layer. The filling rope is formed by twisting two steel wires mutually, the outside of the lapping layer is wrapped with a sheath layer, and the inner wall of the sheath layer is equipped with a plurality of spiral protrusions. In the utility model, by bonding the water-blocking tape between the two layers of fire-resistant mica tapes to form the lapping layer, the fireproof characteristic and water-blocking characteristic of the cable are enhanced, and by arranging the glyph arranged filling ropes on the cable additionally, the mechanical characteristics of the cable, such as the anti-tensile property, are improved, so that various electric energy or signals can be transmitted, and the safe and reliable running of a whole electrical system is realized.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of crosslinked polyetylene insulated safely cleaning power cable.
Background technology:
Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire comprises that mainly bare wire, electromagnetic wire and electrical equipment and electrical are with insulated electric conductor, power cable, telecommunication cable and optical cable.
The utility model is applicable to and exchanges 50HZ, in the circuit of rated voltage 0.6/1kv, supplies the effect of transmission & distribution electric energy.Original cable water resistance in the bigger environment of humidity does not reach requirement, and fire resistance, the mechanical performance of cable do not reach requirement simultaneously.
The utility model content:
To the prior art problem, the purpose of the utility model provides a kind of crosslinked polyetylene insulated safely cleaning power cable, and the water resistance that has solved cable is poor, the problem of fire resistance, bad mechanical property.
The technical scheme of the utility model is following:
Crosslinked polyetylene insulated safely cleaning power cable comprises several conductors, and several conductors are enclosed with insulating barrier outward respectively; It is characterized in that: several conductors outside is enclosed with lapping layer; Lapping layer adopts the wrapped formation of bonding one deck waterstop between the two-layer fire-resistant isinglass belt, is provided with three between lapping layer and the insulating barrier and forms the gasket for packing that isosceles triangle is arranged, and gasket for packing adopts two mutual stranded bunchys of steel wire; The lapping layer outside is enclosed with restrictive coating, and the restrictive coating inwall is provided with several spiral convexity.
Described crosslinked polyetylene insulated safely cleaning power cable is characterized in that: described restrictive coating material adopts halogen-free polyolefin.
Described crosslinked polyetylene insulated safely cleaning power cable is characterized in that: described lapping layer thickness be 0.8-2.5mm.
The utility model has the advantages that:
The utility model adopts the wrapped formation lapping layer of bonding waterstop between the two-layer fire-resistant isinglass belt; Fireproofing of cable characteristic and water resistance characteristic have been strengthened; This outer cable has increased the gasket for packing that isosceles triangle is arranged; Improved the mechanical performances such as stretch-proof of cable, the effect of feasible various electric energy of transmission or signal is that whole electrical system obtains safe and reliable operation.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
