Abstract
The utility model discloses a 35KVXLPE insulating low-smoke halogen-free type grade-A flame-retardant power cable, wherein, a conductor shielding layer, an insulating layer, an insulation shielding layer, a semi-conducting nylon a metal shielding layer, a cushioning layer, a lining layer, a thin-steel tape rat-proofing sheathing layer and a casing layer are arranged outwards from the central conductor of the cable webbing layer,. Of the cable of the utility model, each electrical property conforms to the requiring indexes of GB-12706.3 on 26/35KV cross-linked cables with the highest voltage grade; the flame-retardant property conforms to the group burning test requirements of GB-12666.5-90 on the highest flame retardant grade-A. In addition, the utility model has the rat-proofing function.
Description
The utility model is about a kind of flame-proof power cable, more particularly about a kind of 35KV XLPE insulating low-smoke halogen-free category-A flame-proof power cable.
At present, fire-retardant in order to prevent that sheath that cable fire generally all adopts polyvinyl chloride to add the fire retardant manufacturing from carrying out, but this method rises cable cost significantly; In addition,, can produce a large amount of toxic smogs during high temperature because fire retardant contains a large amount of halogens, contaminated environment, and be added with fire retardant in the sheath and make the electrical performance indexes as insulating material that decline all be arranged, cause electric pressure to descend, influence the use of cable.
Because flame retardant cable is preventing fire spread, improve electric wiring lsafety level aspect and have important role, therefore, fire-retardantization of cable become this developing direction in several years of cable products.The kind of flame retardant cable develops gradually from the earliest polyvinyl chloride insulation and sheath flame retardant cable and to have the low-smoke fireproof cable that smog is low, acid gas is few, the low-smoke halogen-free inflaming-retarding cable kind low until smog, that acid gas is micro-.
Low-smoke halogen-free inflaming-retarding cable is owing to be subjected to the restriction of materials used performance, and its fire resistance is difficult to satisfactory, generally only can reach the fire-retardant rank of C class among the GB-12666.5-90, and the electric pressure of cable generally can not surpass 20KV.
The purpose of this utility model provides a kind of electricapparatus performance requirement that can satisfy the cable use, the insulating low-smoke halogen-free category-A flame-proof power cable that can have the good flame retardancy level again.
The smog generating capacity was little when two of the purpose of this utility model provided a kind of cable fire, and light transmittance is more than 80%, and the halogen acid gas amount that discharges during burning is zero, and the XLPE insulating low-smoke halogen-free category-A flame-proof power cable with anti-plague of rats function.
These and other objects of the present utility model will further describe and embody by following detailed description.
In the utility model, crosslinked polyethylene of the present utility model (XLPE) insulating low-smoke halogen-free category-A flame-proof power cable, from cable center conductor outward, be followed successively by conductor shield, insulating barrier, insulation screen, semiconductive nylon belt, metal screen layer, bed course, lining and protection against rodents armour and restrictive coating, wherein, the protection against rodents armour is the thin steel band of one deck.
In the utility model, described protection against rodents armour Thin Stainless Steel steel band with wrapped form circumvolution on lining, lap is between 5～15 millimeters, metal screen layer is made up of copper wire and copper strips, bed course is high oxygen index hypoxemia halogen-free flameproof glass fiber cloth, cushion thickness is 2.0～3.0 millimeters, and jacket thickness is 2.3～3.0 millimeters.
Product of the present utility model is the thin steel band of overlapping wrapped one deck under protective coverings of cable, and the heat that can under combustion case cable sheath is subjected to is disperseed rapidly like this, has reduced possibility of fire.Simultaneously, this steel belt layer can make its organic material and flame and combustion-supporting gas outside it inside isolated, prevents that effectively combustible species a large amount of under the steel belt layer from producing burning, thereby realizes the purpose of cable-flame retardant.In addition, the cable of this layer steel band after layer can also prevent to lay is subjected to the line outage accident that biting of mouse caused.
The utility model utilizes existing cables manufacturing material and process equipment, by rational material and textural association, the low-smoke non-halogen flame-retardant level of 35KV crosslinked cable is brought up to category-A, and has improved the ability that cable prevents the plague of rats.
Product of the present utility model has following characteristics:
1, every electric property of cable all satisfies the index that requires of highest voltage level 26/35KV crosslinked cable among the GB-12706.3-91.
2, the fire resistance of cable satisfies high flame retardant rank-category-A bunched burning test requirement among the GB-12666.5-90.
3, the smog generating capacity is little during cable fire, and the poorest light transmittance also can reach 80%.
4, the halogen acid gas amount that discharges during cable fire is zero.
5, cable has anti-plague of rats function.
Below further specify the present invention by accompanying drawing and explanation thereof.
