Abstract
The utility model relates to a power cable, in particular to a low-smoke zero-halogen flame-retardant polyolefin insulating sheath flame-retardant cable. The low-smoke zero-halogen flame-retardant polyolefin insulating sheath flame-retardant cable consists of a copper core, a calcium oxide layer and a low-smoke zero-halogen flame-retardant polyolefin insulating sheath, and is characterized in that: the copper core is arranged inside, the calcium oxide layer wraps the copper core, and the low-smoke zero-halogen flame-retardant polyolefin insulating sheath externally wraps the calcium oxide layer. The cable provided by the utility model has the ability of preventing or delaying flame occurrence or spreading.
Description
Technical field
The utility model relates to power cable, is specially halogen-free and low-smoke flame-retardant polyolefin insulating sleeve 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 halogen-free and low-smoke flame-retardant polyolefin insulating sleeve flame retardant cable that flame takes place or spreads to the defective of existing cable.
Concrete technical scheme of the present invention is following:
Halogen-free and low-smoke flame-retardant polyolefin insulating sleeve flame retardant cable; Form by copper core, cao layers, halogen-free and low-smoke flame-retardant polyolefin insulating sleeve; It is characterized in that: the copper core is interior, and cao layers wraps up the copper core, and the halogen-free and low-smoke flame-retardant polyolefin 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---halogen-free and low-smoke flame-retardant polyolefin insulating sleeve.
Embodiment
Below in conjunction with embodiment the utility model is described further.
Halogen-free and low-smoke flame-retardant polyolefin insulating sleeve flame retardant cable is made up of copper core, cao layers, halogen-free and low-smoke flame-retardant polyolefin insulating sleeve, and the copper core is interior, and cao layers wraps up the copper core, and the halogen-free and low-smoke flame-retardant polyolefin insulating sleeve is at the outerwrap cao layers.Cao layers thickness is 2 millimeters, and halogen-free and low-smoke flame-retardant polyolefin insulating sleeve thickness is 3 millimeters.
The utlity model has the ability that stops or delay the flame generation or spread.
