Abstract
The utility model discloses a fire-resistant chlorosulfonated polyethylene electric power cable for a boat, which comprises two conductors, wherein fire-resistant layers and insulation layers are respectively and sequentially coated outside the two conductors, the two conductors coated with the insulation layers are mutually twisted into a beam, the twisting intercept ratio is smaller than 13 times, a belt coating layer is coated outside the formed beam, an armor layer is coated outside the belt coating layer, the armor layer is formed by weaving bare copper wires into a net shape, a sheath layer is formed outside the armor layer through extrusion molding, sheath materials and the armor layer are formed into a whole through extrusion molding, a fire-resistant coating is coated outside the sheath layer, and the thickness of the fire-resistant coating is 0.1-0.3mm. The fire-resistant chlorosulfonated polyethylene electric power cable has the advantages that the structure is novel, the fire-resistant coating layer is coated outside the sheath layer, the flame-retardant performance of the cable is improved, in addition, the cable does not contain halogen, and harmful gas or corrosive gas can not be generated during the combustion.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of chlorosulfonated polyethylene sheath ship power cable of fire safe type.
Background technology:
Though wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application very extensively relates to industries such as electric power, building, communication, manufacturing, and is all closely related with each department of national economy.Electric wire is one of important channel of initiation fire, according to incompletely statistics, accounts for 35% because of what electric wire caused in the fire of China's generation in 2002, and this can not be ignored by the fire that electric wire causes.The disaster that fire brings to the mankind is heavy, and loss is huge, and along with the development of economy and urban construction, fire damage is in rising trend, and therefore equal prevention of fires is very paid attention to both at home and abroad.
Flame retardant cable comprises power cable, control cable, optical cable, line for building and data cable, is used for key project and personnel and the intensive places of equipment such as underground railway, power station, chemical plant, ships, skyscraper, information industry.The fire performance of previous shipboard cable is relatively poor, can not satisfy the real work demand.
The utility model content:
The purpose of the utility model provides a kind of chlorosulfonated polyethylene sheath ship power cable of fire safe type, and fire performance is enhanced, and is applicable to be used for electric power transfer on the ships, has guaranteed the stability of transmission.
The utility model technical scheme following:
The chlorosulfonated polyethylene sheath ship power cable of fire safe type comprises two conductors, and two conductors are enclosed with flame retardant coating, insulating barrier outward successively respectively; It is characterized in that: the mutual stranded bunchy of two conductors of wrap insulate layer, the twisting pitch ratio is less than 13 times, and the outside is enclosed with belting layer behind the bunchy; Belting layer is wrapped with armour; Armour adopts bare copper wire to be woven into netted formation, and the outer extrusion moulding of armour has restrictive coating, and sheath material is in aggregates through extrusion moulding and armour; The restrictive coating outside is enclosed with one deck fire resistant coating, and fire resistant coating thickness is 0.1-0.3mm.
The chlorosulfonated polyethylene sheath ship power cable of described fire safe type is characterized in that: it is ethylene-propylene rubber that described insulating barrier adopts material.
The chlorosulfonated polyethylene sheath ship power cable of described fire safe type is characterized in that: described restrictive coating material adopts chlorosulfonated polyethylene.
The advantage of the utility model:
1. do not contain halogen, do not produce pernicious gas and corrosive gas.
2. be enclosed with one deck fire resistant coating in the restrictive coating outside, improved the fire resistance of cable.
3. do not contain heavy metals such as lead, do not contain environmental hormone, not contaminated soil.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The chlorosulfonated polyethylene sheath ship power cable of fire safe type comprises 1, two conductor of two conductors, 1 outer flame retardant coating 2, the insulating barrier 3 of being enclosed with respectively successively; Two conductors, the 1 mutual stranded bunchy of wrap insulate layer 3, the twisting pitch ratio is less than 13 times, and the outside is enclosed with belting layer 4 behind the bunchy; Belting layer 4 is wrapped with armour 5, and armour 5 adopts bare copper wire to be woven into netted formation, and armour 5 outer extrusion moulding have restrictive coating 6; Sheath material is in aggregates through extrusion moulding and armour, and restrictive coating 6 outsides are enclosed with one deck fire resistant coating 7, and fire resistant coating 7 thickness are 0.1-0.3mm; It is ethylene-propylene rubber that insulating barrier 3 adopts material, and restrictive coating 6 materials adopt chlorosulfonated polyethylene.
