Abstract

The utility model discloses an antistatic oil resistance type control cable, characterized in that a conductor employs a tinned soft copper wire, the conductor is extruded with an insulating layer made of an ETFE material to form an insulating wire core, and a cable core is formed by twisting a plurality of insulating wire cores to form a cable; an inner sheath layer formed by extruding a TPV material and an armor layer formed by braiding a galvanized steel wire are arranged on the outside of the cable core orderly, and an outer sheath layer made of a TPU elastic material is extruded on the outside of the armor layer. The antistatic oil resistance type control cable of the utility model not only has excellent electrical performance, mechanical physical performance and softness performance, but also has the characteristics of antistatic, oil resistance, wear resistance, high/low temperature resistance, flame retardation, fireproof etc., and is suitable for moving control connecting wires under the harsh environments of petroleum and chemical fields.

Description

Anti-static oil-resistance type control cable

Technical field

The utility model relates to a kind of electrical equipment control cable, relates in particular to a kind of anti-static oil-resistance type control cable, belongs to technical field of electric wires and cables.

Background technology

Petroleum chemical industry, because its environmental condition is harsh, reliable and secure property is strict, the cable that this type of field is used has proposed higher specification requirement.

Anti-static oil-resistance type control cable mainly is applicable in oil tank, oil well and the large-scale oil vessel environment to naked light safety requirements extra-high-speed and uses, and directly contacts for a long time or be immersed in the oil to be connected transmission of control signals as electric meter with sensing.Because such cable needs characteristics such as flexibility, cold resistance, resistance to wear, high strength preferably, cable is in use reeled repeatedly and is launched, and does not influence the electrical property of cable.In order to guarantee that cable has desirable electric property, mechanical and physical performance, is suitable for the characteristic of specific (special) requirements; Need carry out necessary optimization to material, structural design that cable is used; Could satisfy the requirement in its field, but not aim at the control cable that adapts to this requirement in the prior art.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point; Not only have good electric property, mechanical and physical performance and softness; Also have characteristics such as antistatic, oil resistant, wear-resisting, anti-height/low temperature, fire-retardant fireproof, be exclusively used in the requirement that adapts to anti-static oil-resistance type electrical control connecting line under oil, the chemical field adverse circumstances.

The utility model technical solution problem adopts following technical scheme:

The design feature of the utility model anti-static oil-resistance type control cable is that conductor adopts the tin annealed copper wire intertwist body, and on said conductor, extruding with ETFE is the insulating barrier formation insulated wire cores of material; Constitute cable conductor by the stranded stranding of a plurality of insulated wire cores; Set gradually from inside to outside to extruding sheath that TPV TPV material forms, constituting armour and extrude the external sheath layer that polyurethane TPU elastomeric material forms at the skin of said cable conductor by the zinc-coated wire braiding.

The design feature of the utility model anti-static oil-resistance type control cable is that also said conductor adopts the 5th type or the 6th type of conductor structure in the GB/T 3956-2008 standard.

Compared with present technology, the utility model beneficial effect is embodied in:

1, conductor adopts the tin annealed copper wire lay configuration in the utility model, and bending radius is little, has improved the flexibility of cable; Simultaneously, adopt tin annealed copper wire, can prevent effectively that bare copper wire is prone to oxidation and makes resistance increase the causing loose contact of cable joint place play electric spark or heating breaking out of fire;

3, the insulating barrier in the utility model has adopted ETFE (F40) material, has that intensity and specific insulation are higher, good insulation preformance, cold resistance be good, premium properties such as density is little, in light weight;

4, the sheath in the utility model forms for thermoplastic rubber TPV extrudes, and elastic properties of materials is good, flexibility is good, can finely play the effect of buffering extraneous pressure;

5, the armour in the utility model adopts the design of zinc-coated wire braiding structure, can play on the one hand and carry cable and loaded article weight, also plays the effect of anti-magnetic disturbance on the other hand;

6, the external sheath layer in the utility model is a material with polyurethane TPU elastomer; Not only have antistatic, oil resistant characteristic; Also have environmental protection, safety, recyclable repeated use, special adverse circumstances such as also having humidity simultaneously, can adapt to high salinity, difference variation is big.

Description of drawings

Fig. 1 is the utility model structural representation.

Label among the figure: 1 conductor, 2 insulated wire cores, 3 sheaths, 4 armours, 5 external sheath layers.

Embodiment

Referring to Fig. 1, in the present embodiment, conductor 1 adopts tin annealed copper wire twisting body, and the insulating barrier that on conductor 1, extrudes ETFE (F40) material constitutes insulated wire cores 2; Constitute cable conductor by a plurality of insulated wire cores 2 stranded strandings; Outside cable conductor, set gradually armour 4 from inside to outside, and extrude the external sheath layer 5 that polyurethane TPU elastomeric material forms for extruding sheath 3 that TPV TPV material forms, constituting by the zinc-coated wire braiding.

In the practical implementation, conductor adopts the 5th type or the 6th type of conductor structure in the GB/T 3956-2008 standard.
