Communication systems are all transmitted through optical fiber cables, and outdoor overhead methods must be considered when laying long-distance communication optical cables.
The main types of photovoltaic power generation system cables are: photovoltaic special cables, control cables, power cables, communication cables, radio frequency cables
Optical Power Ground Wire (OPGW) can not only transmit communication and transmission line maintenance information within the power system, but also serve as a high-frequency channel, telecontrol signal and communication channel for power system relay protection.
The construction of overhead transmission line project is characterized by "many points and wide areas, large amount of high-altitude work, most of which belong to field work and long construction period",
If you want to buy insulated cables, how to distinguish their quality needs to be considered from many aspects.
Traditional communication lines have been difficult to adapt to the development requirements of the new era.
ABC cable: Aerial Bunch cable, including 1-core, 2-core, 3-core, 4-core: Covered ine wre, Dupex senvce dcp,
The use of wires and cables is extremely extensive, which is related to the safety of lives and property of thousands of households.
Scope of application of 35kV and below overhead insulated cables: it is applicable to copper core, aluminum core or aluminum alloy core weather resistant polychlorinated,
