Combined Transformer (Z)NTO-LP-NTZ-6(10)-IV for Open Distribution Systems

Combined transformers NTOLP-NTZ-6(10)-IV UHL1, T1 and ZNTOLP-NTZ-6(10)-IV UHL1, T1 are designed for installation in open switchgear and other electrical installations and are component parts.Transformers are manufactured in climatic versions "UHL" or "T", placement category "1" according to GOST 15150-69. Transformers are designed for total mechanical load from wind speed of 40 m/s, ice with ice wall thickness of 20 mm and from pulling of wires not more than 500 N (50 kgf). The position of transformers in space is vertical, with primary leads upwards.

The maximum deviation from the vertical axis is not more than 30°. Transformers intended for use in systems of normal operation of nuclear power plants (hereinafter referred to as NPs) belong to class 4 according to 2.6 NP-001. Transformers intended for use in the safety important system of normal operation of nuclear power plants belong to class 3 and have a classification designation.
