With the strong growth of my country’s national economy, the speed of various infrastructure, capital construction, and real estate development has accelerated. It is a historical necessity to use mining aerial bundled cables(abc) as the main supply, distribution, and trunk lines in various buildings and facilities. Therefore, construction units, design units, and construction units are seeking more advanced, more economical, superior performance, less effective space, and shorter construction period power supply construction technology and methods. It is also under such historical environmental conditions that prefabricated branch cables have entered my country’s architectural electrical stage in strides.
1) In the middle and high-rise buildings, prefabricated branch cables can be widely used in various middle and high-rise buildings such as residential buildings, office buildings, office buildings, commercial buildings, teaching buildings, scientific research buildings, etc., as the main and trunk cables for power supply and distribution use;
2) In airports and ports, it is used as the main cable for airport runway lighting, port terminal lighting, and power supply and lighting in building facilities;
3) It can be used as lighting power supply in tunnels; it can be used as lighting and power supply network in mines;
4) In the transformation and construction of urban power grids, as the main, kydl_yyyb trunk line mining cables can be buried or overhead;
5) In the modern standard factory building, it is used as the main and trunk cable for mining;
6) In various buildings, facilities, buildings, halls, halls, venues, and even sports facilities, swimming pools, etc., it can be used as main and trunk mining aerial bundled cables BS 7870.
7) Prefabricated branch cables can be used in various other occasions where mining cables are used, such as main and trunk lines of power systems such as ships and ships.
Pre-branch cables have many advantages:
1) The cost of insulation treatment of branch joints is greatly reduced;
2) On-site construction costs are greatly reduced;
3) On-site construction cycle and time are greatly shortened;
4) Reduced on-site construction personnel and equipment; reduced technical requirements for construction personnel;
5) Not restricted by the space and environmental conditions of the construction site;
6) The insulation performance of the branch connector is consistent with that of the cable body, with superior insulation performance and high reliability;
7) It has higher seismic, waterproof and fire resistance performance;
8) The power supply is safe and reliable, and the one-time effective opening rate can reach 100%;
9) Wide application range, many varieties and specifications;
10) Users can conveniently choose cables of various specifications, models, cross-sections, and lengths as the main and branch cables;
11) It has more intuitive maintenance operability.
