CN203787137U - Flat cable for drilling platform - Google Patents

Abstract

The utility model discloses a flat cable for a drilling platform. The flat cable is formed by aluminum conductor wire cores, a wrapping tape layer, a non-magnetic metal armored layer, a copper strip armored layer, a chlorosulphonated polyolefin sheath layer, a butyronitrile insulating layer and nickel conductor wire cores. Four groups of the aluminum conductor wire cores are twisted together and extruded at the inner part of the wrapping tape layer, the inner part of the wrapping tape layer is also extruded with two groups of the nickel conductor wire cores, the outside of the wrapping tape layer is wrapped by a layer of the non-magnetic metal armored layer, the outside of the non-magnetic metal armored layer is wrapped by a layer of the copper strip armored layer, the outside of the copper strip armored layer is wrapped by a layer of the chlorosulphonated polyolefin sheath layer, and the outside of the chlorosulphonated polyolefin sheath layer is wrapped by a layer of the butyronitrile insulating layer. The flat cable is advantaged by light weight, convenient transportation, good shielding effect, low laying temperature, good cold resistance, and good waterproof effect, the allowing bending radius of the cable is eight times of the external diameter of the cable, and the cable can bear the voltage with alternating current 50 HZ and 3.5 kV/5 min and is not broken down.

Description

A kind of drilling platforms flat cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of drilling platforms flat 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 purpose of this utility model is to provide that a kind of cold resistance is good, the drilling platforms flat cable of good water-proof effect.

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

The utlity model has in sum following beneficial effect: this cable is light, convenient transport, 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.

Wherein: 1, aluminium conductor core; 2, belting layer; 3, nonmagnetic metal armour; 4, copper strips armour; 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 cable, it is made up of aluminium conductor core 1, belting layer 2, nonmagnetic metal armour 3, copper strips armour 4, chlorosulfonated polyolefin restrictive coating 5, butyronitrile insulating barrier 6 and nickel conductor thread core 7.Described aluminium conductor core 1 has four groups, twist together and be extruded in belting layer 2 inside, described belting layer 2 inside are also extruded with two groups of nickel conductor thread cores 7, outside described belting layer 2, wrap up one deck nonmagnetic metal armour 3, outside described nonmagnetic metal armour 3, wrap up one deck copper strips armour 4, outside described copper strips armour 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 utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
