Pre-branch cables

The pre-branch cable is a cable that prefabricates the branch line according to the user's design drawings when the factory produces the main cable. It is a new technology product in recent years.

The pre-branch cable consists of 4 parts: 1, trunk cable; 2, branch line; 3 branch connector: 4 related accessories, and has 3 types: common type, flame-retardant type (ZR), fire-resistant type (NH). Pre-branch The cable is an alternative product for the busway power supply in high-rise buildings. It has the advantages of reliable power supply, convenient installation, good waterproofness, small building area, low failure rate, low price, maintenance-free maintenance, etc. It is suitable for AC rated voltage of 0.6\/ In 1KV distribution lines. Widely used in vertical power supply in high and middle-rise buildings, residential buildings, commercial buildings, hotels, hospitals, and also in power supply systems such as tunnels, airports, bridges, and highways.

advantage:

1, Excellent shock resistance, air tightness, water resistance and fire resistance

2, The trunk cable conductor has no joint, good continuity, reducing the probability of failure

3. Adopt advanced fully mechanized crimping technology to avoid the influence of human factors

4. High customizability, the branch location can be set according to the needs of the distribution point of the power distribution system

5. The contact resistance of the branch body is extremely small, and it is not affected by thermal expansion and contraction

6. Reduce power distribution costs and engineering costs, with high economic indicators and obvious comprehensive benefits

7. The installation is simple and the construction period is short. Compared with the closed busway, the installation time is greatly reduced.

8. It is maintenance-free after installation and operation, and does not require any maintenance and maintenance in normal times.

main advantage:

Can significantly reduce power distribution costs

(1) Compared with the closed busway, the price is cheaper and the project cost is reduced, and the economic index is high, the comprehensive benefit is obvious, and the specifications are complete, flexible selection, and arbitrary combination.

(2) The branch head can arbitrarily set the branch position according to the needs of the distribution point of the power distribution system

Low installation environment requirements and easy construction

(1) The occupied building area is small, and there is no requirement for the space size of civil works

(2) The installation is simple, the installation is convenient, and the use environment is low. It can be directly laid in the cable trench, in the special cable shaft of the building, or in different cable trays, and the installation accuracy is low.

(3) Compared with the closed bus duct, the direction of the cable is random and the bending radius is small, which greatly reduces the difficulty of construction and reduces the space size.

(4) The installation labor intensity is small, the construction period is short, only one tenth of the closed busway installation

Excellent shock resistance, air tightness, water resistance and fire resistance

(1) It has excellent shock resistance. Generally, the closed mechanical connection bus duct is installed in parallel with the wall. When the wall is subjected to vibration, the joints of the closed bus duct are loosened, and the prefabricated branch cable will not be affected. In particular, no measures are required when passing through settlement joints in buildings

(2) Good airtightness and waterproofness, can operate normally in a humid environment, and can also be laid in the open air and buried in the soil

(3) When the fire-resistant prefabricated branch cable is burning, keep 90Min normal power transmission operation

Maintenance free

(1) After the branch cable is installed according to the specified method, the one-time opening rate is high

(2) The whole system of prefabricated branch cables in normal operation does not need any maintenance and maintenance in peacetime

(3) The accident repair is simple in the later stage, and the maintenance cost is extremely low
