A compact European style cable branch box for ring network connection in 10kV cable distribution systems.
Designed for electrical distribution systems that require stable operation, clear circuit protection, and practical installation for industrial, commercial, utility, and infrastructure projects.
Dongfang Electric Power (Shandong) Co., Ltd. supports product selection by voltage level, rated current, installation environment, cabinet structure, cable connection method, and project documentation needs.
European Style Cable Branch Box
Product Overview
The European style cable branch box is cable engineering equipment widely used in power distribution systems. Its main features are double-sided doors and the use of insulated wall bushings as the connection busbar. It has a short length, clear cable arrangement, and three-core cables do not require large-span crossing. The cable connectors generally use 630A bolted fixed cable joints compliant with DIN47636.
Functions and Features
| Feature 1 | Fully insulated, fully sealed, fully protected and all-weather construction. |
|---|---|
| Feature 2 | Flexible incoming and outgoing lines; in practical applications up to eight branches can be arranged. |
| Feature 3 | Resistant to flooding, pollution, condensation, frost and corrosion. |
| Feature 4 | Small size, compact structure, simple installation and convenient operation. |
| Feature 5 | Live indicators can be installed to remind operators that lines are energized. |
| Feature 6 | Cable-type short-circuit fault indicators can be installed for quick fault detection. |
| Feature 7 | Enclosure material options include mirror stainless steel, ordinary steel plate military green and aluminum-zinc coated steel plate. |
Main Application
It is widely used in 10kV cable distribution networks in urban industrial parks, urban residential communities, urban commercial centers, mining areas and large enterprises such as steel, automotive, petroleum, chemical and cement plants. It is an ideal device for ring-network connection and urban grid reconstruction.
