Abstract
The utility model discloses a flame retardant control cable having a framework lining. The flame retardant control cable having the framework lining comprises four tinned copper conductors, wherein the four tinned copper conductors are externally and respectively wrapped in a low smoke zero halogen polyethylene and a reinforced layer formed by a cotton sheet, the low smoke zero halogen polyethylene insulation layers are internally filled with high-temperature resistance magnesium oxide powder, the tinned copper conductors are embedded in the tightly-compacted high-temperature resistance magnesium oxide powder, the multiple cotton sheet reinforced layers are externally and commonly wrapped in an isolation layer formed by wrapping high flame retardant fiber belts in an overlapping mode, the isolation layer is internally provided with a crossing rubber framework, an outer wall of the crossing rubber framework is twined by and wrapped in a flame retardant fiber filament layer, the four tinned copper conductors are respectively erected on the crossing rubber framework with intervals, and the isolation layer is externally and sequentially wrapped in an armored layer formed by stranding a steel rope, a reinforced belt formed by bonding a fireproof belt and a polyester belt, and a low smoke zero halogen polyethylene outer sheath. The flame retardant control cable is ingenious in the improved structure, is internally provided with the multiple flame retardant isolation layers additionally, has strong flame retardant performance, is provided with the rubber framework having the flame retardant property and further improves integral toughness.
Description
technical field:
The utility model relates to electric wire, is mainly a kind of flame-proof control cable with skeleton liner.
background technology:
Traditional flame-proof control cable, in the time that fire occurs, has halogen acid gas to cause corrosion to instrument and equipment, also easily affects the performance of cable simultaneously; And fire-retardant separator is not set in the flame-proof control cable of existing low smoke and zero halogen, poor fire, and the physics anti-pressure ability of cable inside a little less than.
utility model content:
Technical problem to be solved in the utility model is to provide a kind of flame-proof control cable with skeleton liner, its architecture advances is ingenious, sets up multi-layer fire-retarded fire-resistant separator in cable inside, and fire resistance is strong, and be provided with the rubber skeleton of flame-retarding characteristic, the toughness of whole cable is improved.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of flame-proof control cable with skeleton liner, include four tinned copper conductors, it is characterized in that: four described tinned copper conductors are coated with respectively low smoke and zero halogen polyethylene layer outward, low smoke and zero halogen polyethylene layer is coated with the reinforced layer being made up of web, in described low smoke and zero halogen polyethylene layer, be filled with high temperature oxidation resisting magnesium powder, described tinned copper conductor is embedded in tightly compacted high temperature oxidation resisting magnesium powder; The reinforced layer that described multiple web forms is coated with the separator of the overlapping wrapped formation of high flame retardant fabric strip outward jointly, is provided with cross rubber skeleton in described separator, and four described tinned copper conductors respectively isolating frame are located on cross rubber skeleton; Reinforcing band and low smoke and zero halogen outer protective polyethylene cover that described separator is coated with successively the armour stranded by steel cable outward, is sticked together by fire resistant belt and polyester belt.
On the outer wall of described cross rubber skeleton, voluble wrapping has one deck fire resistance fibre silk.
It is the place such as 450/750V and following control, monitoring loop and protection circuit that the utility model is applicable to ac rated voltage, is specially adapted to the coefficient of safetys such as nuclear power station, subway, theater and requires high important place.Cable core long-term work temperature of the present utility model can reach 90 DEG C, has extended the useful life of cable.
The utility model has the advantages that:
The utility model architecture advances is ingenious, sets up multi-layer fire-retarded fire-resistant separator in cable inside, and fire resistance is strong, and is provided with the rubber skeleton of flame-retarding characteristic, and the toughness of whole cable is improved.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1, a kind of flame-proof control cable with skeleton liner, include four tinned copper conductors 1, the outer low smoke and zero halogen polyethylene layer 2 that is coated with respectively of four described tinned copper conductors 1, low smoke and zero halogen polyethylene layer 2 is coated with the reinforced layer 3 being made up of web, in described low smoke and zero halogen polyethylene layer 2, be filled with high temperature oxidation resisting magnesium powder 4, described tinned copper conductor 1 is embedded in tightly compacted high temperature oxidation resisting magnesium powder 4; The outer separator 5 that is jointly coated with the overlapping wrapped formation of high flame retardant fabric strip of reinforced layer 3 that described multiple web forms, in described separator 5, be provided with cross rubber skeleton 6, four described tinned copper conductors 1 separate respectively and are erected on cross rubber skeleton 6; The described outer reinforcing band 8 that is coated with successively the armour 7 stranded by steel cable, be sticked together by fire resistant belt and polyester belt of separator 5 and low smoke and zero halogen outer protective polyethylene cover 9.
On the outer wall of described cross rubber skeleton 6, voluble wrapping has one deck fire resistance fibre silk 10.
