Abstract

The invention discloses a flat copper conductor cable for a drilling platform. The flat copper conductor cable is composed of copper conductor cable cores, a nickel strip shielding layer, a nonmagnetic metal armor layer, an aluminum strip shielding layer, a chlorosulfonated polyolefin protective layer, a butyronitrile insulating layer and nickel conductor cable cores. The four copper conductor cable cores are twisted together, the nickel strip shielding layer is arranged outside the combination of the four copper conductor cable cores in an extruded mode, the nickel strip shielding layer is also arranged outside the two nickel conductor cable cores in an extruded mode, the nonmagnetic metal armor layer is wrapped outside the nickel strip shielding layer, the aluminum strip shielding layer is wrapped outside the nonmagnetic metal armor layer, the chlorosulfonated polyolefin protective layer is wrapped outside the aluminum strip shielding layer, and the butyronitrile insulating layer is wrapped outside the chlorosulfonated polyolefin protective layer. The cable is light in weight, convenient to transport, good in shielding effect, low in laying temperature, high in cold tolerance and good in waterproofing effect; the allowable bending radius of the cable is eight times the outer diameter of the cable; the cable can bear a 3.5 Kv alternating voltage at the frequency of 50 HZ for 5 minutes without breakdown.

Description

A kind of drilling platforms flat copper conductor cable

Technical field

The present invention relates to field of cables, relate in particular to a kind of drilling platforms flat copper conductor cable.

Background technology

At present, be applied to the cable of drilling well, tunnel, submarine laying use, all very high to the each side quality requirement of cable, because very important of fail safe in these fields, generally not admit of potential safety hazard to exist, in these fields, just should use so that some are good in cold resistance, good water-proof effect, cable that resistance to pressure is strong, can better ensure and improve fail safe.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide that a kind of cold resistance is good, the drilling platforms of good water-proof effect flat copper conductor cable.

The present invention takes following technical scheme to realize: a kind of drilling platforms flat copper conductor cable, it is made up of copper conductor core, nickel strap screen, nonmagnetic metal armour, aluminium strip screen, chlorosulfonated polyolefin restrictive coating, butyronitrile insulating barrier and nickel conductor thread core.Described copper conductor core has four groups, twist together and be extruded in nickel strap screen inside, described nickel strap screen inside is also extruded with two groups of nickel conductor thread cores, outside described nickel strap screen, wrap up one deck nonmagnetic metal armour, outside described nonmagnetic metal armour, wrap up one deck aluminium strip screen, outside described aluminium strip screen, wrap up one deck chlorosulfonated polyolefin restrictive coating, outside described chlorosulfonated polyolefin restrictive coating, wrap up one deck butyronitrile insulating barrier.

The present invention has following beneficial effect in sum: this cable is light, convenient transportation, shield effectiveness is good, lays temperature low, cold resistance is strong, good water-proof effect, the permission bending radius of this cable is the outside diameter of cable 8 times; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.

Accompanying drawing explanation

Fig. 1 is cross-sectional structure schematic diagram of the present invention;

Wherein: 1, copper conductor core; 2, nickel strap screen; 3, nonmagnetic metal armour; 4, aluminium strip screen; 5, chlorosulfonated polyolefin restrictive coating; 6, butyronitrile insulating barrier; 7, nickel conductor thread core.

Embodiment

As shown in Figure 1, a kind of drilling platforms flat copper conductor cable, it is made up of copper conductor core 1, nickel strap screen 2, nonmagnetic metal armour 3, aluminium strip screen 4, chlorosulfonated polyolefin restrictive coating 5, butyronitrile insulating barrier 6 and nickel conductor thread core 7.Described copper conductor core 1 has four groups, twist together and be extruded in nickel strap screen 2 inside, described nickel strap screen 2 inside are also extruded with two groups of nickel conductor thread cores 7, outside described nickel strap screen 2, wrap up one deck nonmagnetic metal armour 3, outside described nonmagnetic metal armour 3, wrap up one deck aluminium strip screen 4, outside described aluminium strip screen 4, wrap up one deck chlorosulfonated polyolefin restrictive coating 5, outside described chlorosulfonated polyolefin restrictive coating 5, wrap up one deck butyronitrile insulating barrier 6.

The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
