Product Description

Execution Standard
Reference standards GB/T12706 and JG/T147 are adopted.

Product Features and Main Uses
Widely used in power distribution systems of high-rise buildings, office buildings, hospitals, shopping malls, factories, etc. The main trunk cable conductor has no joints, the branch cable conductor joints have a reasonable structure, very low contact resistance, unaffected by thermal expansion and contraction, excellent seismic resistance, good airtightness and waterproofness, fire resistance, and can supply power normally in humid environments. It occupies a small area and is simple and convenient to install.

Applications

Pre-branch cables are widely used for vertical power supply in electrical shafts of high-rise buildings, residential buildings, shopping malls, hotels, and hospitals. They are also suitable for power supply systems in tunnels, airports, Bridges, highways, etc. Its main advantages include:

Reliable power supply: The main cable conductors of the pre-branch cable have no joints, reducing the number of fault points.

Easy installation: The branch joints are prefabricated through mechanical crimping technology to ensure the continuity of the conductors and the stability of contact resistance. · Good water resistance: It can operate normally with power supply in a humid environment and can also be laid outdoors or buried in the soil. · Seismic resistance: The joint is not affected when the wall vibrates, and has good seismic resistance.

Fire resistance: Fire-resistant products meet fire protection requirements and can maintain normal power supply for 90 minutes during combustion.

Space utilization optimization: The compact structure of branch points reduces the space occupied by cable trays or pipelines, making it particularly suitable for narrow areas such as vertical shafts in high-rise buildings.

Adapt to complex scenarios: Customizable multi-level branches are available to meet the extremely high requirements for power supply continuity in places such as hospitals and data centers.

Other jacket materials/colors can be provided upon request, such as CSP/PCP/NBR/PVC.

Double-layer jackets with reinforced fibers in the middle are available as an optional configuration.
