The high-voltage comprehensive oil-filled cable for high strength offshore drilling has relatively high tensile strength, ensures normal operation of the cable in subsea oil exploitation, the cable has excellent electrical performance, high signal transmission frequency, good shielding effects, and strong anti-electromagnetic interference capability.

Description

High strength offshore drilling is with the comprehensive oil-filled cable of high pressure
Technical field
The utility model relates to family expenses communication electric power equipment field, relates in particular to a kind of oil-filled cable.
Background technology
Increasing along with people's demand to information in productive life, more and more widely, mechanics of communication is advanced by leaps and bounds, and presents information technology prosperity scene in the ascendant.Extensively adopt in each field under the demand of information technology, should need and the communication product of giving birth to is broken through the soil one after another like rain the back spring bamboo.Yet, on the great equipments such as the Aero-Space high in big, the fire-retardant requirement of high low temperature difference variation, that communicating requirement is strict, naval vessel, offshore platform, oil exploration, power plant, little because of the communication products demand, quality requirement is strict, performance constantly changes requirement because occasion is different, so far aspect high-end communication products especially communications cable product aspect also form industry standard and the product line of specialty.
Existing ocean engineering, large scale electrical power unit, oil production equipment, large-scale suspender or supervisory control system generally adopt separate cable system, this class oil-filled cable is mostly main considers electric power conveying, communication, performance such as anti-interference, tensile strength to cable itself is not special attention, tensile strength has just just satisfied basic standard mostly, when cable has specific demand, use the cable of regular tenacity, reliability will be affected.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high strength offshore drilling with the comprehensive oil-filled cable of high pressure, this cable utilizes corrosion resistant sulfuration butadiene-styrene rubber as oversheath, and tension steel wire increase tensile strength is set in oversheath, guaranteed the operate as normal of cable under specific condition.
The utility model is achieved in that a kind of high strength offshore drilling is with the comprehensive oil-filled cable of high pressure, comprise conductor, the tension steel wire, insulating barrier, conductive shielding layer, filler, inner sheath, shield layer and oversheath, described conductor is hollow structure, be provided with oil duct in the conductor, the outer wrapped conductive shielding layer of conductor, described insulating barrier is wrapped outside conductive shielding layer, the outer wrapped aluminum foil shielded of insulating barrier becomes heart yearn, wrapped inner sheath in turn from inside to outside behind three stranded strandings of heart yearn, shield layer and oversheath, described filler is filled in the space between the heart yearn, offer an oilhole that communicates with insulating barrier every a segment distance on the described conductor, described tension steel wire is arranged in the oversheath, and described oversheath is sulfuration butadiene-styrene rubber.
Described conductive shielding layer is conductive paper.
Described insulating barrier is immersion oil brown paper.
Described filler is flame-proof polyethylene.
Described inner sheath is flame retardant rubber.
Described shield layer is the zinc-coated wire braid.
This utilizes corrosion resistant sulfuration butadiene-styrene rubber as oversheath with the comprehensive oil-filled cable of high pressure in the utility model high strength offshore drilling, and the tension steel wire is set in oversheath increases tensile strength, can bear the load more than 3000 kilograms, guaranteeing that cable can operate as normal when submarine oil is exploited, has excellent electric property, signal transmission frequency height, shield effectiveness is good, and anti-electromagnetic interference capability is strong.
