product details

Product Description

Product Standards

GB/T10228-2015 GB1094.11-2007

Rated high voltage: 10 (10.5, 11, 6, 6.3, 6.6) kV

Rated low voltage: 0.4kV

Tap range: non-excitation voltage regulation (±5%, ±2x2.5%)

On-load voltage regulation: (±4x2.5%)

Connection group: Dyn11 or Yyn0

Insulation level: LI75AC35/AC5

Note: When the maximum ambient temperature is >40°C and the altitude is >1000m, corrections should be made according to the relevant provisions of the national standard. Ask the user to put it forward when ordering.
