Abstract
Disclosed in the utility model is a power flat cable for drilling well. The power flat cable is composed of copper conductor core wires, a carbon fiber belt layer, a chlorosulfonated polyolefin sheath layer, a silicone rubber insulation layer and a copper tape armored layer. Three groups of copper conductor core wires are arranged and are stranded together and then are extruded inside the carbon fiber belt layer. The carbon fiber belt layer is coated with the chlorosulfonated polyolefin sheath layer; the chlorosulfonated polyolefin sheath layer is coated with the silicone rubber insulation layer; and the silicone rubber insulation layer is coated with the copper tape armored layer. The provided cable with the light weight can be transported conveniently; the laying temperature is low; the cold tolerance performance is good; 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
Technical field
The utility model relates to field of cables, relates in particular to a kind of drilling well electric power 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 drilling well electric power flat cable of good water-proof effect.
The utility model takes following technical scheme to realize: a kind of drilling well electric power flat cable, it is made up of copper conductor core, carbon fiber belt, chlorosulfonated polyolefin restrictive coating, silicone rubber insulation layer and copper strips armour.Described copper conductor core has three groups, twist together and be extruded in carbon fiber belt inside, outside described carbon fiber belt, wrap up one deck chlorosulfonated polyolefin restrictive coating, outside described chlorosulfonated polyolefin restrictive coating, wrap up one deck silicone rubber insulation layer, outside described silicone rubber insulation layer, wrap up one deck copper strips armour.
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, copper conductor core; 2, carbon fiber belt; 3, chlorosulfonated polyolefin restrictive coating; 4, silicone rubber insulation layer; 5, copper strips armour.
Embodiment
As shown in Figure 1, a kind of drilling well electric power flat cable, it is made up of copper conductor core 1, carbon fiber belt 2, chlorosulfonated polyolefin restrictive coating 3, silicone rubber insulation layer 4 and copper strips armour 5.Described copper conductor core 1 has three groups, twist together and be extruded in carbon fiber belt 2 inside, outside described carbon fiber belt 2, wrap up one deck chlorosulfonated polyolefin restrictive coating 3, outside described chlorosulfonated polyolefin restrictive coating 3, wrap up one deck silicone rubber insulation layer 4, outside described silicone rubber insulation layer 4, wrap up one deck copper strips armour 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.
