10/24/35kM High Voltage Cable Branch Box (European Style)

General Information

High-voltage cable branch boxes are widely used for node connections in 10kV, 24kV, and 35kV cable systems. They are the main electrical equipment for gathering and tapping cables after they exit the switch cabinet. The cable joints of the tap box are tightly insulated with high-grade insulated imported rubber and have no exposed live parts; the switches in the tap box with switches are all SF6 insulated load switches.

The tap box is designed for outdoor maintenance-free operation, which is safe and reliable. Its protection level reaches IP33, and the underground tap can withstand flooding. This product is widely used in distribution networks in urban industrial areas, residential areas, commercial centers, mining areas, large enterprises such as steel, automobiles, petroleum, chemicals, cement, and other occasions. It is especially suitable for urban power grid transformation projects and can greatly save electrical equipment and Invest in cables to improve power supply reliability.

Product Features

1. Compact structure, small footprint, easy installation, easy operation and maintenance-free.
2. The box body is all made of metal steel plate or stainless steel plate with a thickness of 2mm. It adopts anti-corrosion design and special spray painting treatment to operate reliably in harsh environments (life span ≥ 30 years).
3. Outdoor all-weather, fully protective structure, suitable for high temperature, severe cold, flood immersion, and high dust areas.
4. Fully sealed and fully insulated structure, no insulation distance required, all high-voltage live parts are silicone rubber or EPDM prefabricated cable connectors, effectively ensuring personal safety.
5. Flexible combination can make the number of outlet branches reach seven, which can be combined with SF. The load switch forms a ring network for power supply, fully meeting various wiring requirements.
6. The cable joint can be used as a switch, which can be plugged and unplugged under load to break the 200A load current.
7. After installing the fault indicator, circuit faults can be quickly detected.
8. The one-time investment is small, the cable length is reduced, the building area is not occupied, and money is saved.
9. The cable connector used complies with IEEE386 standard.
10. All cable joints are suitable for cross-linked polyethylene insulated cables. The 200A cable joint is suitable for cables with a cable cross-section of 35mm²-180mm²; the 600A cable joint is suitable for cables with a cable cross-section of 25mm²-500mm².

Technical Parameters

Usage Environment

2. Wind speed: equivalent to 34m/s (not more than 700Pa).
3. Humidity: The daily average relative humidity is not greater than 95%; the monthly average relative humidity is not greater than 95%.
4. Shockproof: horizontal acceleration is not greater than 0.4m/s2, and vertical acceleration is not greater than 0.15m/s2.
5. The inclination of the installation site: no more than 3°.
6. Installation environment: The surrounding air should not be significantly contaminated by corrosive, flammable gases, water vapor, etc., and there should be no severe vibration at the installation site.

Configuration Plan

European Cable Branch Box Structure Example Diagram

 

If the cable distribution box cannot be placed due to site limitations, the cable joints can be directly combined to form multiple cable branches (no busbars are required, see the connection method below) and placed in the cable trench or other locations.

Example 1: Four incoming and outgoing lines.

Each phase consists of two European-style front joints and two European-style rear joints, connected by a European-style butt bushing in the middle. The ends of the European rear connectors are sealed with insulators and semi-conductive end caps.

Example 2: Two in and three out.

Each phase consists of three European-style front joints and two European-style rear joints, connected with European-style butt bushings in the middle. The ends of the European rear connectors are sealed with insulators and semi-conductive end caps.
