The main advantages of power cables
Can significantly reduce distribution costs
(1) Compared with enclosed busbar trunking, it is cheaper in price, reduces engineering costs, has higher economic indicators, obvious comprehensive benefits,
and has complete specifications, flexible selection, and any combination
(2) The branch head can set the branch position arbitrarily according to the needs of the distribution points in the distribution system
Low installation environment requirements and simple construction
(1) Occupying a small building area, there are no requirements for the spatial size of civil engineering
(2) Easy to lay, easy to install, low environmental requirements, can be directly laid in cable trenches, specialized cable shafts in buildings, or in different cable trays,
with low installation accuracy
(3) Compared with enclosed bus ducts, the cable direction is arbitrary and the bending radius is small, greatly reducing the construction difficulty and reducing the
space size
(4) The installation labor intensity is low, the construction period is short, and it is only one tenth of the time when installing enclosed bus ducts
Excellent seismic resistance, airtightness, waterproofing, and fire resistance
(1) It has excellent seismic resistance and is generally a closed mechanical connection bus duct. Due to parallel installation based on the wall, when the wall is shaken,
the joints of the closed bus duct become loose. Prefabricated branch cables are not affected, especially when passing through settlement joints in buildings, and no
measures are needed
(2) Good airtightness and waterproofing, able to operate normally in humid environments, and can also be laid outdoors or buried in soil
(3) Fire resistant prefabricated branch cables maintain normal power transmission operation for 90 minutes under combustion conditions
