Details.
10kV Dry Type: This transformer is suited to urban power network upgrades and is used in urban power grids, high-rise buildings, business centres, theatres, hospitals, tunnels, metro systems, airports and similar sites. The SC(B)10/11 epoxy cast dry-type transformer has high mechanical and electrical strength and good heat resistance. It is cast in class F epoxy resin with filler after vacuum thin-film degassing.
Features
- Strong short-circuit withstand, low loss, low no-load current, strong impact resistance, low partial discharge, low noise, good heat sinking capacity.
- Performance parameters exceed GB and IEC standards.
- Safe, flame retardant, fireproof and non-polluting; can be installed directly at the load.
- Maintenance-free, easy to install, low operating costs.
- High reliability, high mechanical strength.
- Good seismic capability.
- Good anti-moisture & anti-corrosion features.
- Good overload capability: without forced-air cooling it can run at 120% load long term.
- Suitable for substations in densely populated, cramped urban areas.
Normal service conditions
Altitude: ≤1000m
Ambient air temperature
Maximum temperature: +40°C
Minimum temperature: -25°C (Outdoor dry type power transformer)
Minimum temperature: -5°C (Indoor dry type power transformer)
Highest monthly average temperature: +30°C
Highest annual average temperature: +20°C
Relative air humidity: ≤90%; there should be no water on the coil surface. The three-phase supply voltage should be approximately symmetrical and the voltage waveform approximately sinusoidal.
