Type and Signification

Performance Characteristic: · This transformer and 'g' type transformer, no-load current aver-age reduce more than 70%: About 3 no-load loss on average 30% lower.
· J B/T 1008-1 999 standard is compared, the noise is small about 7 d B
· Oil level and high and low voltage winding temperature rise.20 K lower than the temperature rise limit about a 1 3 K, has the certain load capacity
· Anti-short circuit ability, high reliability.

Structure Characteristic: · Core: structure of three phase three pillar type rolled inside and outside the box, column for multistage ladder circular cross section; Core.coiling by vacuum annealing after removing stress; Trough bending clip, pull the screw tighten body; Core surface coating is special glue ensure that core deformation, do not rust.
· Winding and body: low voltage winding for 1 -6 wire and around four layer or double layer cylindrical (500 kVA and below) or spira winding (630 kVA and above): Anaerobic copper conductor adopts control: High and low voltage winding layer ask insulation tape for lind lattice point; High voltage winding axial oil the tao and the empty between high and low pressure oil gap to stay shade structure; lron yoke insulation and trapezoidal block is an organic whole, make body even under pressure: Body structure of new type hanger position, vertical and horizontal orientation, ensure displacement of solid body.
· Tank: adopt corrugated tank, sealed structure, not leak, maintenance free.
