Abstract

The invention relates to a novel armored cable. The novel armored cable comprises five insulated cable cores, wherein a wrapping tape layer is wound outside the insulated cable cores, an inner sheath layer is extruded outside the wrapping tape layer, a steel wire armor layer in the same direction of the insulated cable cores is arranged outside the inner sheath layer, an outer sheath layer is extruded outside the steel wire armor layer and filling layers are arranged in gaps in the wrapping tape layer. The insulation stability of the cross-linked polyethylene insulating layers and the silicon rubber outer sheath layer is good, the tensile strength and compressive strength of the galvanized medium-carbon steel wire armor layer are high, the bending radius is large, the novel armored cable can be effectively prevented from being bitten by animals such as mice, and the service life is long.

Description

A kind of Novel armored cable

Technical field

The present invention relates to power cable field, be specifically related to a kind of novel armoured cable.

Background technology

Armoured cable is contained in the metal sleeve of insulating material by the conductor of unlike material; be processed to flexible solid assembly; be mainly used in the transmission of the industry dynamic powers such as metallurgy, chemical industry, electric power, machinery; common power cable is generally all laid in cable trough or cable testing bridge; do like this can not effectively prevent mouse bite and mechanical external force to the destruction of cable; in order to protect the structure of cable; ensure normal electric property, to cable increase armour just seem very important.

Summary of the invention

The invention provides a kind of good stability that insulate, armoured cable that compression strength is high.

For achieving the above object, the present invention adopts following technical approach: a kind of armoured cable, comprise five with insulated core, insulated core outward turning is wound with belting layer, inner restrictive coating is extruded with outside belting layer, be provided with outside inner restrictive coating and insulated core steel wire armor layer in the same way, be extruded with external sheath layer outside steel wire armor layer, in described belting layer, gap place is provided with packed layer.

Further, insulated core forms by extruding crosslinked polyetylene insulated layer outside copper conductor.

Further, steel wire armor layer adopts zinc-plated middle carbon finer wire.

Further, external sheath layer adopts silastic material.

Further, packed layer adopts fire-retardant compound glass towline.

Beneficial effect: the crosslinked polyetylene insulated layer of the present invention and silicon rubber external sheath layer insulation good stability, zinc-plated middle carbon LWA light wire armoured tensile strength and compression strength is high, bending radius is large, effectively can also prevent biting of the animals such as mouse, long service life.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

In figure: 1, copper conductor 2, crosslinked polyetylene insulated layer 3, packed layer 4, belting layer 5, inner restrictive coating 6, steel wire armor layer 7, external sheath layer

Embodiment

Its structure as shown in the figure: a kind of armoured cable, comprise five with insulated core, insulated core outward turning is wound with belting layer 4, inner restrictive coating 5 is extruded with outside belting layer 4, be provided with outside inner restrictive coating 5 and insulated core steel wire armor layer 6 in the same way, be extruded with external sheath layer 7 outside steel wire armor layer 6, in described belting layer 4, gap place is provided with packed layer 3; Insulated core forms by extruding crosslinked polyetylene insulated layer 2 outside copper conductor 1; Steel wire armor layer 6 adopts zinc-plated middle carbon finer wire; External sheath layer 7 adopts silastic material; Packed layer 3 adopts fire-retardant compound glass towline.

The crosslinked polyetylene insulated layer of the present invention and silicon rubber external sheath layer insulation good stability, zinc-plated middle carbon LWA light wire armoured tensile strength and compression strength is high, bending radius is large, effectively can also prevent biting of the animals such as mouse, long service life.
