Medium Voltage Cable Branch Box

Medium Voltage Cable Branch Box

The Medium Voltage Cable Branch Box is used for connection and branching in 10kV cable distribution lines with a rated current of 630A.
It is mainly applied where a trunk cable needs to split into several branch circuits in an urban medium-voltage network.
Concentrating cable joints inside one enclosure can reduce the number of dispersed cable connection points along the route.

Cable connection and branching

Typical Structure

Mainly without switch

 

Insulation and Functional Choice:

 

 

  • Air insulation or solid insulation can be selected according to the technical scheme.
  • The typical configuration is a no-switch structure, with the main task focused on cable connection and branching rather than line switching.
  • For projects that do not require operating switches at the branch point, this structure keeps the equipment function centered on cable distribution.

 

Network Planning Value:

 

 

  • The product can be used as an alternative to traditional cable joint-well arrangements where a packaged branch point is preferred.
  • It suits underground or cable-based urban distribution systems and trunk-line nodes that divide power toward multiple directions.
  • Buyers should confirm the number of incoming and outgoing cables, branch circuits, and whether switch functionality is required before final selection.

 

Custom Branch Arrangement:

 

 

  • Custom production can cover cable circuit quantity, air or solid insulation, incoming and outgoing direction, and customer technical drawings.
  • OEM/ODM cooperation is available after the technical scheme is confirmed.
  • When ordering a Medium Voltage Cable Branch Box, provide the branch quantity, cable interfaces, insulation method, installation approach, purchase quantity, and project cable-line drawing.

 

Inspection and Transport:

 

 

  • Raw materials and principal electrical parts are inspected before production, followed by multiple checks during fabrication and assembly.
  • Finished equipment receives electrical performance testing and 100% electrical performance inspection before packing. Third-party factory inspection can be arranged by the purchaser.
  • Export units use rust-prevention and transport protection appropriate to the enclosure and internal components, with reinforced solid-wood cases for shipment.
  • Customized specifications generally require 20–35 working days. EXW and FOB trade terms are supported.
