Abstract

The utility model discloses a tensile-resistance flat cable which comprises a conductor, an insulated wire core and a sheath. The conductor is wrapped with a flame-retardant cross-linked polyolefin insulating layer. A copper-wire armor layer is woven outside the insulating layer. The copper-wire armor layer is wrapped with a flame-retardant cross-linked polyolefin insulating layer II to form an insulated wire core. Three insulated wire cores are combined to form a cable core. A steel wire rope is arranged in the cable core. A copper-wire armor layer II is woven outside the cable core. The copper-wire armor layer II is wrapped with a high-flame-retardant anti-corrosion flexible neoprene sheath layer. The tensile-resistance flat cable satisfies performance indexes of an elevator cable, such as low smoke, flame retardance, shock resistance and the like. Meanwhile, the cable provided by the utility model also has advantages of anti-twisting performance and tensile resistance.

Description

A kind of stretching resistance flat cable

Technical field

The utility model relates to a kind of stretching resistance flat cable, belongs to electric wire field.

Background technology

Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.

The cable for elevator of China just starts development and exploitation as far back as the nineties in last century.Under the upsurge of real estate and elevator industry development, factory of a lot of domestic enterprise all starts to develop elevator cable.But the structural design of cable is mostly more single, along with era development, the requirement that environmental protection etc. are higher, the environmental protection characteristic to elevator cable and multifunctional all have also proposed specific requirement.

Traditional cable for elevator for anti-twist in actual working environment be the topic being difficult to resolve always.

Utility model content

The utility model provides a kind of stretching resistance flat cable simple in structure, has met the low cigarette that elevator cable has, the performance index such as fire-retardant, shockproof, and this cable also has advantages of anti-twist, stretching resistance simultaneously.

Scheme of the present utility model is as follows: a kind of stretching resistance flat cable, comprise conductor, insulated wire cores and sheath, the outer wrapped flame-proof cross-linking polyolefin insulation layer of described conductor, described insulating barrier weaves copper wire armored layer outward, the outer wrapped flame-proof cross-linking polyolefin insulation layer II of copper wire armored layer forms insulated wire cores, three insulated wire cores are combined into cable core, and steel wire rope is set between cable core; Cable core weaves copper wire armored layer II outward, the outer corrosion-resistant flexible chloroprene rubber sheath layer of wrapped high flame retardant of described copper wire armored layer II.

Further, to amass be 0.75～2.5 mm to described cross-sectional area of conductor ².

Further, described conductor is by stranded the forming of 10-50 root copper wire.

Further, described insulated wire cores is four.

The utility model adopts flat type structure, cable center is used steel wire rope, strengthen the pulling force in cable pulling process, sheath adopts fire-retardant acrylonitrile-butadiene rubber, after this material modification and possess the performances such as wear-resisting, anti-tear, warp resistance, shockproof, corrosion-resistant, high flame retardant, can meet the requirement that various environment move.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of stretching resistance flat cable, comprise conductor 1, insulated wire cores and sheath 7, the outer wrapped flame-proof cross-linking polyolefin insulation layer 2 of described conductor 1, the described outer braiding copper wire armored of insulating barrier 2 layer 3, the outer wrapped flame-proof cross-linking polyolefin insulation layer II 4 of copper wire armored layer 3 forms insulated wire cores, three insulated wire cores are combined into cable core, and steel wire rope 5 is set between cable core; Cable core weaves copper wire armored layer II 6 outward, the described corrosion-resistant flexible chloroprene rubber sheath layer 7 of the outer wrapped high flame retardant of copper wire armored layer II 6.

It is 0.75～2.5 mm that described cross-sectional area of conductor amasss ², described conductor is by stranded the forming of 10-50 root copper wire, and described insulated wire cores is four.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
