2. by the bracing piece being fixed on the inside of layer of silica gel, its bracing piece is fixed on cable inner chamber using segmentation structure, can
To avoid cable from being in inflexibility state, the flexibility of cable is added, while by bracing piece cable core is separated and right
Cable is supported, and can effectively increase the compression dynamics of cable, and avoiding cable from being pressurized or be embedded in underground for a long time causes to deform,
The effect of energization or the signal transmission of internal cable core is influenceed, it is more practical.
3. bracing piece surface is fixedly connected with silica gel sheath simultaneously, silica gel sheath can reasonably be protected to layer of silica gel, kept away
Exempt from when cable is pressurized, bracing piece damage layer of silica gel, influence the whole service life of cable, and layer of silica gel is entered by rubber layer
Row protection, and rubber layer surface is bonded with fluorescence coating by epoxide-resin glue and rubber layer inner chamber is fixed with nylon wire silk screen, Buddhist nun
Imperial filament net can increase the intensity of rubber layer, increase the toughness of rubber layer, after long-term use timely rubber layer oxidation, nylon
Filament net can still be protected to layer of silica gel.
4. look for line taking cable to be relatively easy under conditions of dark by fluorescence coating, and by transparent polyvinyl chloride insulating cement
Band is bonded to fluorescence coating, can improve the anti-solarization performance of fluorescence layer surface, so as to effectively increase the overall use of cable
It is life-span, more practical.
