Application Scope of 6–13 kV Transformers
These transformers belong to the category of medium‑voltage distribution transformers, mainly used for voltage conversion and power supply in urban/industrial distribution networks, industrial and mining enterprises, and infrastructure.
1. Main Application Fields
1. Urban Power Grid Distribution
– Power supply for residential communities, commercial complexes, office buildings, hospitals, schools and other end‑users
– Main transformers / distribution transformers in urban ring main units, box‑type substations and distribution rooms
2. Industry & Manufacturing
– Internal power supply for factories, workshops and production lines
– Small and medium‑sized industrial loads in mining, metallurgy, chemical industry, machinery manufacturing, etc.
– Centralized power distribution in industrial parks and development zones
3. Infrastructure & Public Buildings
– Traction / auxiliary power supply systems for rail transit (subways, light rails)
– Main / backup power supply for airports, high‑speed rail stations, data centers
– Street lighting, water supply and drainage pump stations, sewage treatment plants
4. New Energy & Supporting Facilities
– Box‑type step‑up / distribution transformers for photovoltaic and wind power projects
– Centralized power supply transformers for energy storage stations and EV charging stations
5. Commercial & Special Scenarios
– Hotels, shopping malls, cold chain logistics, supermarkets
– Temporary power supply transformers for construction sites
2. Typical Working Parameters
– High voltage side: 6 kV / 10 kV / 13 kV
– Low voltage side: 0.4 kV (380/220 V)
– Function: Step down medium‑voltage grid power to low‑voltage power for civil / industrial use
