The 33KV overhead insulated cable is an overhead conductor equipped with an insulating layer and a protective sheath.
It is a special cable manufactured by a process similar to that of cross-linked cables.
It is a new power transmission method between overhead conductors and underground cables.
Conductors generally use AAC, AAAC, ACSR twisted wires.
The insulating material is 70°C PE or 90°C XLPE.
Features
1.Greater power distribution
Compared with the 10kV distribution network, the distribution capacity of the 33kV medium-voltage distribution network is increased by one times, the power supply radius can be doubled.
2.Lower power loss
Compared with the 10kV distribution network,the voltage loss is 50% of 10kV, and the power loss is reduced 75% lower.
3.Good safety performance
It is simple in structure, safe and reliable, and has good mechanical and insulating properties.
In urban and rural power distribution networks, power outages and electric shock accidents are often caused by the contact of overhead bare wires with trees along the line. Using this cable can avoid such accidents, and even in the case of downed poles and dropped wires, it can still continue Power supply, safe and reliable.
Application
It provides 120/220V aerial service for tem services on construction sites, as point of service (pole to service entrance), as secondary cable (pole to pole), or as street lighting.
Construction
The structure of this product is similar to that of the traditional Central Asian cable. The single-core cable has shielding and sheath, and the multi-core composite bundle cable has an insulated or non-insulated steel strand carrying line. In addition, the phase separation method of the multi-core cable mostly uses convex ridges.
