Abstract
The utility model relates to a power cable, particularly to a calcium oxide flame-retardant cable for a flame-retardant PVC (polyvinyl chloride) insulating sheath. The calcium oxide flame-retardant cable for the flame-retardant PVC (polyvinyl chloride) insulating sheath consists of a copper core, a calcium oxide layer and the flame-retardant PVC insulating sheath; the calcium oxide flame-retardant cable is characterized in that the copper core is arranged inside and coated by the calcium oxide layer, and the calcium oxide layer is coated on the outside of the flame-retardant PVC insulating sheath. The calcium oxide flame-retardant cable disclosed by the utility model has the ability of preventing or retarding flame from occurring or spreading.
Description
Technical field
The utility model relates to power cable, is specially flame-proof PVC insulating sleeve calcium oxide flame retardant cable.
Background technology
It has often been said that floods and fires have no mercy, since the mankind found fire, fire had not only quickened the development of human civilization, has also brought destruction to human civilization, and the civilization in how many ancient times is destroyed in big fire.Equally, fire also can burn comprehensive wiring system, and electric power transfer is interrupted.Simultaneously, if cable produces a large amount of toxic gases and flue dust in combustion process, can produce influence greatly to personnel's escape so, even become safe hidden danger.Electric power transfer is carried high pressure, big electric current itself also is the place of causing the condition of a fire easily.
Summary of the invention
The utility model provides a kind of effective prevention or delays the flame-proof PVC insulating sleeve calcium oxide flame retardant cable that flame takes place or spreads to the defective of existing cable.
Concrete technical scheme of the present invention is following:
Flame-proof PVC insulating sleeve calcium oxide flame retardant cable is made up of copper core, cao layers, flame-proof PVC insulating sleeve, it is characterized in that: the copper core is interior, and cao layers wraps up the copper core, and the flame-proof PVC insulating sleeve is at the outerwrap cao layers.
The utlity model has the ability that stops or delay the flame generation or spread.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is the structural representation of the utility model.
Wherein, 1---copper core, 2---cao layers, 3---flame-proof PVC insulating sleeve.
Embodiment
Below in conjunction with embodiment the utility model is described further.
Flame-proof PVC insulating sleeve calcium oxide flame retardant cable is made up of copper core, cao layers, flame-proof PVC insulating sleeve, and the copper core is interior, and cao layers wraps up the copper core, and the flame-proof PVC insulating sleeve is at the outerwrap cao layers.Cao layers thickness is 2 millimeters, and flame-proof PVC insulating sleeve thickness is 3 millimeters.
The utlity model has the ability that stops or delay the flame generation or spread.
