Abstract
The invention relates to a halogen-free low-smoke flame-retardant fire-resistant control cable. The cable comprises a plurality of insulating wire cores and a control wire core which is arranged at the central portion of the cable core. The insulating wire cores are composed of copper conductors and insulating layers coating the copper conductors. The control wire core is composed pf a copper conductor and a shielding layer coating the conductor. The outer side of the insulating wire cores is provided with a wrapping tape through extrusion to form a cable core. The outer side of the cable core is provided with an inner sheath, a metal armoured layer and an outer sheath from inside to outside successively. According to the invention, advantages of simple structure, low smoke, non-toxic performance, green and environmental protection, long service life and low production cost can be realized.
Description
Technical field
The present invention relates to a kind of control cables, relate in particular to a kind of halogen.
Background technology
Along with the develop rapidly of China's economy, the skyscraper of China, subway, nuclear power station, shipbuilding industry, photoelectron communication etc. develop at a speed unheard of before especially, and the consumption of electric wire also increases rapidly thereupon.
Summary of the invention
The present invention provides a kind of simple in structure, LSZH, environmental protection, long service life, halogen that production cost is low in order to overcome the above problems.
Technical scheme of the present invention is: described cable comprises some insulated wire cores and is arranged on the control core at cable core center, described insulated wire cores is made up of the insulating barrier of copper conductor and copper conductor outer cladding, described control core is made up of the screen of copper conductor and conductor outer cladding, described insulated wire cores extrudes twining package tape outward and forms cable core, and described cable core is followed successively by inner sheath, metal armouring layer and oversheath outward from the inside to the outside.
Some described insulated wire cores deciles are evenly arranged on controls core periphery.
Described inner sheath and oversheath are pvc sheath.
The present invention is simple in structure, LSZH, environmental protection, long service life, production cost are low.
