Oil-Immersed 630KVA 1000KVA Pre-Installed Box-type Substation
HENTG POWER Oil-Immersed 630KVA 1000KVA Pre-Installed Box-type Substation 6KV 10KV YB Compact Transformer Distribution
Typical Application Scenario
The HENTG POWER Oil-Immersed Pre-Installed Box-Type Substation is widely applied in industrial parks, urban infrastructure projects, renewable energy sites, and commercial developments where fast installation, limited space, and reliable medium-voltage power distribution are required.
Example Scenario - Industrial Manufacturing Zone
In a newly developed industrial zone, power demand must be established quickly to support production lines, lighting systems, and auxiliary equipment. Traditional substations require long construction cycles and complex civil works. The YB compact box-type substation provides a plug-and-play solution, allowing the power system to be energized shortly after delivery and positioning.
Product Introduction
The HENTG POWER YB Series Pre-Installed Box-Type Substation integrates:
- Medium-voltage switchgear (6kV / 10kV)
- Oil-immersed distribution transformer (630kVA or 1000kVA)
- Low-voltage distribution panel
into a single compact enclosure, factory-assembled and tested before shipment.
