CN203760113U - Elliptic cable core-contained cable of mine drilling platform - Google Patents

Abstract

The utility model discloses an elliptic cable core-contained cable of a mine drilling platform. The cable is composed of copper conductor wire cores, a polyester fiber layer, a silicone rubber insulation layer, a nickel belt shielding layer, a butyronitrile insulating layer, a copper belt armoured layer and a galvanized steel tape armored layer. Five groups of copper conductor wire cores are arranged and are twisted together; the polyester fiber layer coats the outsides of the copper conductor wire cores; the polyester fiber layer is coated with the silicone rubber insulation layer; the silicone rubber insulation layer is coated with the nickel belt shielding layer; the nickel belt shielding layer is coated with the butyronitrile insulating layer; and the butyronitrile insulating layer is coated with the copper belt armoured 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 ten 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 mine drilling platforms ellipse cable core cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of mine drilling platforms ellipse cable core 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 cold resistance are good, 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 mine drilling platforms ellipse cable core cable of good water-proof effect.

The utility model takes following technical scheme to realize: a kind of mine drilling platforms ellipse cable core cable, it is made up of copper conductor core, layer of polyester fiber, silicone rubber insulation layer, nickel strap screen, butyronitrile insulating barrier, copper strips armour and galvanized steel strip armour.Described copper conductor core has five groups, outside twisting together, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck silicone rubber insulation layer, outside described silicone rubber insulation layer, wrap up one deck nickel strap screen, outside described nickel strap screen, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, 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 10 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, layer of polyester fiber; 3, silicone rubber insulation layer; 4, nickel strap screen; 5, butyronitrile insulating barrier; 6, copper strips armour; 7, galvanized steel strip armour.

Embodiment

As shown in Figure 1, a kind of mine drilling platforms ellipse cable core cable, it is made up of copper conductor core 1, layer of polyester fiber 2, silicone rubber insulation layer 3, nickel strap screen 4, butyronitrile insulating barrier 5, copper strips armour 6 and galvanized steel strip armour 7.Described copper conductor core 1 has five groups, outside twisting together, wrap up one deck layer of polyester fiber 2, outside described layer of polyester fiber 2, wrap up one deck silicone rubber insulation layer 3, outside described silicone rubber insulation layer 3, wrap up one deck nickel strap screen 4, outside described nickel strap screen 4, wrap up one deck butyronitrile insulating barrier 5, outside described butyronitrile insulating barrier 5, wrap up one deck copper strips armour 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.
