three-phase transformers utilize three-legged cores.
Only high quality grain oriented silicon steel is used.
Core steel is precision cut and stacked for reduced noise and losses.
Cores are clamped with heavy steel brackets.

4.2 所有的线圈绕组是高质量漆包线(铜或铝可用);类220℃保温利用整个绕线过程;所有变压器的设计与有效的散热大幅降温管道;每个线圈浸渍和在聚酯树脂清漆烘烤;设置在所有分离式变压器标准±5%或±2×2.5%抽头。

All coil windings are of high quality magnet wire (copper or aluminum are available).
Class 220°C insulation is utilized throughout the coil winding process.
All transformers are designed with substantial cooling ducts for effective cooling.
Every coil is impregnated and baked in polyester resin varnish.
Standard ±5% or ±2×2.5% taps are provided on all isolation type transformers.
4.3 标准的箱体由重规格钢板。控制变压器选购指南
通风孔被布置为使得每个标准外壳适于任一NEMA或CSA类型1,类型2,或类型3R应用程序。
所有机箱被设计以最小化与带电部件意外接触的可能性,并限制下落颗粒的访问到变压器。
所有标准机柜完成了ASA61灰色粉末涂层。

Standard enclosures are constructed of heavy gauge steel.
Ventilation openings are arranged so that each standard enclosure is suitable for either NEMA or CSA Type 1, Type 2, or Type 3R applications.
All enclosures are designed to minimize the possibility of accidental contact with live parts and to restrict the access of falling particles into the transformer.
All  standard enclosures are finished in ASA 61 grey powder coating.
