Abstract
The utility model relates to an instrument cable for offshore oil platform, which belongs to cable technical field, and is characterized in that: the wire-core is provided with filling compound and a double-layer wrapping oxygen barrier, which ensures that the cable has high temperature resistance, excellent insulation, high breakdown voltages, high heat resistant index, tensile resistance and anti-mechanical damage, anti-strong-electromagnetic interference and anti-heavy statics properties; while under the situation of being on fire, the cable is highly flame-retardant, highly fire-resistance, oxygen-insulated, non-toxic and smogless and the transparency is 85%, which can help staff evacuate; the utility model has the advantages of simple structure, easy produce and manufacture, smooth and intact appearance, and good capability of usage, which is tested with the 750 DEG C flame sprayed onto the cable; according to the national fire-resistance experimental standard IEC60331:1999, the cable fully reaches specified standard, and can be safely used for fire protection by the staff on the offshore oil platform, so as to have popularization using value and a broad market prospect.
Description
Technical field
The utility model relates to a kind of offshore oil platform power cable, belongs to the cable technology field.
Background technology
Along with rapid development of national economy, imbalance between supply and demand for fear of the domestic shortage of petroleum resources of dominating lifelines of the national economy, the China's oil driller strengthens marine exploitation dynamics, as backing, strive for the basic energy resource of depending on for existence for the country and people with present China technology and economic strength as early as possible more.The strategy of " strengthen the marine site exploration and development, realize the marine oil and gas fast development " that proposes according to the China Petroleum Tenth Five-year plan, the construction of offshore oil platform have also entered gold period.Because the particularity that offshore oil platform requires cable, at present, cable for petroleum flat is generally from national imports such as the U.S., Korea S, raising along with offshore oil platform production domesticization level, the more superior novel offshore oil platform power cable of research and development performance, satisfying the particular requirement of offshore oil platform, is a urgent task of manufacturing enterprise.
Summary of the invention
The purpose of this utility model is exactly for adapting to the demand in market, by improvement to existing cable, provide a kind of and have that high temperature resistant, seawater corrosion resistance, good insulation preformance, puncture voltage height, heat-resistance index are big, the anti-mechanical damage of tension, anti-electromagnetic interference performance be superior, the fire-resistant oxygen barrier of high flame retardant, and nontoxic non smoke, a kind of offshore oil platform power cable that light transmittance is high.
The purpose of this utility model is achieved through the following technical solutions, a kind of offshore oil platform power cable, comprise the wrapped double-deck flame retardant coating of mica tape, crosslinked polyetylene insulated layer of cable core that constitutes that pair of conductors and each root conductor periphery set gradually from inside to outside, the sheath that cable core sets gradually outward from inside to outside, zinc-coated wire braid shield and oversheath, it is characterized in that outside a pair of cable core and between the sheath double-deck wrapped oxygen barrier layer being set, outside a pair of cable core and in the space between the double-deck wrapped oxygen barrier layer high flame retardant Halogen inserts is set.
The wrapped oxygen barrier layer of described bilayer adopts the high flame retardant glass fibre belt.
Described high flame retardant Halogen inserts is a high flame retardant glass rope.
The utility model is rational in infrastructure simple, manufacture easily, cost is low, cable smooth in appearance rounding, serviceability is good, core adopts double-deck fire-resistant and extrudes crosslinked polyetylene insulated layer, inserts and double-deck wrapped oxygen barrier layer are set on the cable core, the zinc-coated wire braid shield, it is high temperature resistant to have guaranteed that cable has, good insulation preformance, the puncture voltage height, heat-resistance index is big, tension is prevented mechanical damage, the characteristics that anti-electromagnetic interference performance is superior are under the situation of breaking out of fire, cable has the fire-resistant oxygen barrier of high flame retardant, nontoxic non smoke, light transmittance helps personnel and withdraws evacuation up to 85%, the fire fighter puts out a fire and rescues trapped personnel and property, reduces loss as far as possible.According to the fire-resistant experimental standard IEC60331:1999 of country, 750 ℃ flames are sprayed on carry out combustion experiment on this cable, reach the specified standard requirement fully, satisfy the safe in utilization of offshore oil platform personnel fire-fighting, excellent popularization using value and vast market prospect are arranged.
