PBT tube OPGW Construction
The core of aluminium clad PBT tube OPGW has structure of stranding pattern,when the multiple optical fiber PBT tubes are into cable,a layer of seamless aluminium tube will be clad on it which act as the protection tube of optical fiber metal and then stranding one or more aluminium clad steel wires or aluminium alloy wires outside it,It eliminates the worries about the electrochemecal corrosion different metals and has very high application value.
PBT tube OPGW Cable Structure
PBT tube OPGW Characteristics
1.Seamless aluminium tube has uniform texture,consistent with the texture of the whole ground aluminium clad steel wire,no electrochermical corrosion.
2.good fatigue resistance profit by consistence of texture of the whole ground wire.
3.Optical fiber of aluminium tube OPGW are exist in PBT tube,the core which is clad with a layer of thermal insulation material,with good thermal insulation effect and good protection effect of fiber optics,and short-circuit current has little influence to transmitting of fiber optical.
