Description
Technical field
The utility model relates to the cable technology field, relates in particular to 35kVA class flame-proof power cable technical field, is useful in high pressure for the technology of transmission of electricity field.
Background technology
For improving the lsafety level of electric wiring, the fire-retardant problem of cable causes that more and more people pay close attention to, and fire-retardantization of cable become a comprehensive development direction of China's line cable industry.Accomplish safe and reliable, advanced technology, economical rationality for guaranteeing cable design in the power circuit and operation, prevent the caused fire of cable, reduce the loss that electric wire is caused in fire, many Utilities Electric Co.s regulation is from now in the 35kV power circuit, no matter be the newly-designed circuit or the transformation of old road line, should adopt the flame retardant type cable, and the fire resistance of cable to reach the requirement of category-A regulation in GB/T18380.3-2001 " the burning test method of the bunchy electric wire " standard.The C class can only be accomplished by the domestic many producers of the fire resistance of 35kV cable, if will reach the fire-retardant requirement of category-A, and will be to its flame treatment that insulate, yet, the cable of 35kV has higher anti-electric requirement, and the mixing of any fire retardant is to the medium of insulation, withstand voltage, freely all can bring fatal harm.
Technical scheme
The utility model can satisfy the 35kV flame-proof power cable for a kind of above-mentioned defective that overcomes is provided, and reaches the requirement of category-A regulation in GB/T18380.3-2001 " the burning test method of the bunchy electric wire " standard, the flame-proof power cable of good flame retardation effect.
The utility model comprises the uni-core flame-retardant cable of being made up of conductor, conductor screen, insulation, insulation shielding, copper strips shielding and outer jacket or comprises the fire-retardant unarmored cable that conductor, insulation, shielding, filling and outer jacket are formed or comprise the fire resistant armoured cable that conductor, insulation, shielding, filling, sheath, armour and outer jacket are formed, and is provided with the high flame retardant layer between the insulated wire cores of cable and oversheath.
The high flame retardant layer adopts gluing glass strap, and packed layer adopts flame-retardant shaped packing, and its oxygen index is greater than 30.
The utility model is owing to adopted the high flame retardant layer between the insulated wire cores of cable and sheath; played the not burned purpose of protection insulating barrier; and the high flame retardant layer material has adopted special construction; again owing to the packing material with cable adopts flame-retardant shaped packing; its oxygen index is greater than 30; this cable also has following feature except that satisfying normal electric property and mechanical and physical performance:
1, flame-retarding characteristic: can stop spreading of fire, its fire resistance reaches category-A regulation in GB/T18380.3-2001 " the burning test method of the bunchy electric wire " standard.
2, for the low cigarette category-A flame retardant cable of the low halogen of 35kV: its light transmittance is not less than 30%, and low halogen performance: a, halogen acid gas escaped quantity are not more than 100mg/g during cable fire; B, pH value are not less than 2.5, and conductivity is not more than 30
3, for 5kV low smoke, zero halogen category-A flame retardant cable: its light transmittance is not less than 60%, and Halogen performance: a, no halogen acid gas are overflowed during cable fire; B, pH value are not less than 4.3, and conductivity is not more than
The utility model design science, novel, processing technology is simple, has the good flame effect.
