Description

A kind of marine worker sets cable in stock

Technical field

The utility model belongs to cable production art, in particular to a kind of marine worker sets cable in stock.

Background technique

The transfer to ocean is exploited along with global energy, marine oil and gas engineering is in the ascendant.Due to marine oil and gas engineering It is middle to be full of inflammable and explosive greasy dirt and therefore gas sets cable in stock to marine worker and proposes the requirement of " explosion-proof ".Due to electric spark and Fuel factor is to cause the main contributor of explosion hazard gases explosion, and consider from system wiring angle, since cable is by many distributions Capacitor, inductance equal distribution element are formed, it is made correspondingly to become energy-storage travelling wave tube, therefore inevitable in signals transmission Ground stores certain energy.Once system breaks down, these energy storage will be released in the form of electric spark or fuel factor, The safety of influence system.It is therefore desirable to which cable has low capacitor and low inductance, the charge of cable institute band itself will lack, be not easy Generate electric spark；Secondly, it is desirable that cable has good shielding properties, with excellent anti-external electromagnetic field interference and does not generate pair Outer interference.This requires cables to have the characteristics that low capacitor and low inductance, and has good shielding properties and anti-interference Can, and better than the explosion-proof performance of general common cable.

Utility model content

Technical problem: in order to solve the defects of prior art, the utility model provides a kind of marine worker and sets cable in stock.

Technical solution: the utility model provides a kind of marine worker and sets cable in stock, and structure includes: by 3 core unit groups At cable core, core unit is by extruded insulation layer on the outside of conductor, the then wrapped water blocking tape wrapping layer composition outside insulating layer；Cable core Successively wrap up colour band layer, shielded layer, external sheath layer in outside；The fire-retardant filled layer that blocks water is set between cable core and colour band layer；In color It is axially disposed in belt to there is tension to split reinforcing rib；It is provided with insulating layer of asbestos between external sheath layer on the outside of shielded layer, so that Cable electric property under high temperature (high and cold) environment is stablized, and anti-aging property is prominent, long service life.

As a preferred solution: insulating layer is crosslinked polyetylene insulated layer.

As further preferred scheme: shielded layer is constituted using compound copper-plastics band and proof copper-wire braided.

As further preferred scheme: being brushed with corrosion-inhibiting coating on shielded layer outer surface；So that cable acid and alkali-resistance and corrosion-resistant Performance greatly promotes.

As further preferred scheme: external sheath layer is Halogen cross-linked polyolefin.

The utility model has the advantages that cable thermal insulation property used for intelligent electric network provided by the utility model is superior, and cold-resistant warp resistance, corrosion resistant Erosion, the use being suitble in marine worker equipment.

Detailed description of the invention

Fig. 1 is the structural schematic diagram that the utility model marine worker sets cable in stock.

Specific embodiment

With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that these embodiments are only For illustrating the utility model rather than limitation the scope of the utility model, after having read the utility model, this field Technical staff falls within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.

A kind of marine worker sets cable in stock, and structure includes: the cable core being made of 3 core units, the core unit by 1 outside extruded insulation layer 2 of conductor, then wrapped water blocking tape wrapping layer 3 forms outside insulating layer 2；It is successively wrapped on the outside of the cable core Wrap up in colour band layer 4, shielded layer 5, external sheath layer 6；The fire-retardant filled layer 7 that blocks water is set between the cable core and colour band layer 4；Described Colour band layer 4 in axially disposed there is tension to split reinforcing rib 8；Stone is provided between 5 outside of shielded layer and external sheath layer 6 Cotton thermal insulation layer 9, so that cable electric property under high temperature (high and cold) environment is stablized, anti-aging property is prominent, long service life.

As a preferred solution: insulating layer 2 is crosslinked polyetylene insulated layer.

As further preferred scheme: shielded layer 5 is constituted using compound copper-plastics band and proof copper-wire braided.

As further preferred scheme: being brushed with corrosion-inhibiting coating on 5 outer surface of shielded layer；So that cable acid and alkali-resistance and corrosion-resistant Performance greatly promotes.

As further preferred scheme: external sheath layer 6 is Halogen cross-linked polyolefin.
