Abstract

Disclosed in the utility model is a flat cable for offshore drilling platform. The flat cable consists of tinned copper conductor core wires, a carbon fiber belt layer, a polyester fiber layer, an aluminum belt shielding layer, a butyronitrile insulation layer and a steel tape armoured polyethylene sheath layer; five groups of tinned copper conductor core wires are twisted together and are extruded inside the carbon fiber belt layer; the outside of the carbon fiber belt layer is coated with the polyester fiber layer; the outside of the polyester fiber layer is coated with the aluminum belt shielding layer; and the outside of the aluminum belt shielding layer is coated with the butyronitrile insulation layer. The provided cable is light and can be carried conveniently; the laying temperature is low; the cold tolerance performance is high; and the waterproof effect is good. The allowed bending radius of the cable is eight times larger than the external diameter of the cable; and the cable can bear the 50-Hz alternating current and the voltage of 3.5kv/5min without being broken down.

Description

A kind of offshore drilling platform flat cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of offshore drilling platform 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.

Utility model content

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 offshore drilling platform flat cable of good water-proof effect.

The utility model takes following technical scheme to realize: a kind of offshore drilling platform flat cable, it is made up of tinned copper conductor core, carbon fiber belt, layer of polyester fiber, aluminium strip screen, butyronitrile insulating barrier and steel-tape armouring pe sheath layer, described tinned copper conductor core has five groups, twist together and be extruded in carbon fiber belt inside, outside described carbon fiber belt, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck aluminium strip screen, outside described aluminium strip screen, wrap up one deck butyronitrile insulating barrier.

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

Brief description of the drawings

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, tinned copper conductor core; 2, carbon fiber belt; 3, layer of polyester fiber; 4, aluminium strip screen; 5, butyronitrile insulating barrier; 6, steel-tape armouring pe sheath layer.

Embodiment

As shown in Figure 1, a kind of offshore drilling platform flat cable, it is made up of tinned copper conductor core 1, carbon fiber belt 2, layer of polyester fiber 3, aluminium strip screen 4, butyronitrile insulating barrier 5 and steel-tape armouring pe sheath layer 6, described tinned copper conductor core 1 has five groups, twist together and be extruded in carbon fiber belt 2 inside, outside described carbon fiber belt 2, wrap up one deck layer of polyester fiber 3, outside described layer of polyester fiber 3, wrap up one deck aluminium strip screen 4, outside described aluminium strip screen 4, wrap up one deck butyronitrile insulating barrier 5.

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.
