Abstract
For a tension shielding cable for oil platform, relate to field of cable technology, object is to provide a kind of stretch-proof, the cable that electromagnetic shielding capability is good.It comprises conductor, conductor is wrapped with insulating barrier, insulating barrier is wrapped with internal shield, internal shield is wrapped with bitumen layer, be provided with steel wire floor in bitumen layer, bitumen layer is wrapped with flame retardant coating, and flame retardant coating is wrapped with external sheath layer, described steel wire floor is arranged to the garden type closed by some steel wire encirclings, the gap between described internal shield and bitumen layer is provided with filler.
Description
Technical field
The utility model relates to field of cable technology, provides a kind of tension shielding cable for oil platform.
Background technology
Along with the proposition of the strategy of " accelerate ocean exploration exploitation, realize marine oil and gas fast development ", the construction of offshore oil platform also enters gold period.Because offshore oil platform is to the particularity of cable needs, cable for petroleum flat is all generally from the U.S., the national import such as Korea S, along with the raising of offshore oil platform production domesticization level, domestic urgent to the requirement of offshore oil platform private cable, a kind of new product that super soft high-tensile control cables used for oil platform is developed for the Environment Design of oil platform, cable needs on oil platform is soft, tension, oil resistant, high temperature resistant, low temperature resistant, rub resistance etc., high to the environmental performance demand of cable, screen many employings tinsel establishment of used for oil platform common cable in the past, easily there is exoperidium bulge or prick the problem of threading core in cable shield.
Utility model content
The purpose of this utility model is to provide a kind of stretch-proof, the cable that electromagnetic shielding capability is good.
The utility model is by the following technical solutions to achieve these goals:
A kind of tension shielding cable for oil platform, it comprises conductor, conductor is wrapped with insulating barrier, insulating barrier is wrapped with internal shield, and internal shield is wrapped with bitumen layer, is provided with steel wire floor in bitumen layer, bitumen layer is wrapped with flame retardant coating, flame retardant coating is wrapped with external sheath layer, and described steel wire floor is arranged to the garden type closed by some steel wire encirclings, the gap between described internal shield and bitumen layer is provided with filler.
In technique scheme, described filler is waterstop, and waterstop comprises copper mesh bonding successively, nonwoven fabrics and glass fibre.
In technique scheme, described flame retardant coating comprises mica layer and basalt braid, and basalt braid is wrapped in outside mica layer, and described mica layer thickness is 0.3-0.8mm, and the filament diameter of described basalt braid is 0.3-0.8mm.Basalt braid can be good at mica to wrap up, and mica is not separated when being heated.
In technique scheme, described insulating barrier is polyethylene or polyolefin.
In technique scheme, for external sheath layer adopts thermoplastic elastomer (TPE) TPU material.
Because the utility model adopts above technical scheme, so possess following beneficial effect:
The utility model adopts steel wire encircling distribution to form the electro-magnetic screen layer of closed circle, and steel wire can increase the resistance to tension of cable, and steel wire floor is arranged in bitumen layer, effectively adds the antiseptic power of cable.
Accompanying drawing explanation
Fig. 1 is mechanism map of the present utility model.
