It states and is equipped with cable core inside inner sheath, and cable core lateral wall is enclosed with glass fabric, between the glass fabric two sides
It is fixedly connected with rubber buckle, and glass fabric lateral wall is filled with anti-flame retardant layer.
Further, the inner sheath internal layer has assigned clad strip, and the clad strip other side faces the wall and meditates and is bonded with anti-puncture silk
Stratum reticulare is provided with smokeless cotton between the anti-puncture silk screen layer and anti-flame retardant layer.
Further, the oversheath inner sidewall and inner sheath lateral wall are welded with rubber pad, and pacify between rubber pad
Equipped with spring.
Further, the anti-flame retardant layer is the coating of magnesium hydroxide and active nano magnesium carbonate mixed filler.
Compared with prior art, the utility model has the following beneficial effects:
1. phase mutual friction between cable core convenient for increasing the insulation effect of cable, is avoided by setting glass fabric, and
Bound rubber buckle increases the installation fastness between cable core convenient for will be attached between glass fabric.
2. increasing the change cigarette function of cable by forming using magnesium hydroxide and active nano magnesium carbonate mixed filler
Can, and then the burst size and smoke amount inside cable are reduced, so that Flame Retardancy is improved, it can be effective in combination with smokeless cotton
Trap heat transmission, to play heat insulation.
3. can be effectively reduced compressive strength inside cable, and then cable is protected to use by flexible using spring stress
Safety.
