Embodiment Construction

[0013] Such as figure 1 Shown is a flame-retardant control cable 100 according to the present invention.

[0014] The flame retardant control cable 100 includes a conductor 1 , an insulating layer 2 surrounding the conductor 1 , a shielding layer 3 surrounding the insulating layer 2 , and a sheath 4 surrounding the shielding layer 3 . The flame retardant control cable 100 is a multi-core cable with several conductors 1 inside. The cross section of the conductor 1 is circular, the cross section of the insulating layer 2 is circular, the cross section of the shielding layer 3 is circular, and the cross section of the sheath 4 is circular. The cross sections of the conductor 1 , insulating layer 2 , shielding layer 3 and sheath 4 are concentric circles. Insulation layer 2 is a flame-retardant modified polyolefin irradiated insulation layer, which has high insulation resistance, good withstand voltage, small dielectric coefficient and small influence of dielectric loss temperatu...

Abstract

The invention relates to a flame retardation control cable. The flame retardation control cable comprises conductors, insulation layers respecitvley encircled outside the conductors, a shielding layer encircled outside the insulation layer and a sheath encircled outside the shielding layer, wherein the insulation layers are flame retardation modification polyolefin irradiation insulation layers. The flame retardation control cable solves a problem of flame retardation incapability of a control cable, further avoids damage to a human body and equipment during use of the control cable and gains time for rescue and escape.

Description

【Technical field】 [0001] The invention relates to a cable, in particular to a control cable. 【Background technique】 [0002] The control cable is mainly used in the automation control system and the automation connection system, to transmit control and control, and to complete the corresponding instructions. Traditional control cable insulation materials mainly include polyvinyl chloride and cross-linked polyolefin, and most of the sheaths are polyvinyl chloride. This kind of cable has no flame-retardant properties due to non-metallic materials, and the insulation and sheath materials are quickly destroyed in a fire environment, causing the control system to fail, and burning and releasing toxic gases such as halogens, which pose a threat to equipment and personal safety. , The released smoke screen seriously affects people's rescue and escape, and cannot be used in office buildings, residential buildings, schools and other areas where population and equipment are concentra...
