Product Advantages


Core:


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° mitring and steps overlapping structure is used for core production, enable the effectiveness of reducing no-load loss and no-load current.

HV winding:


HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.

LVwinding:


LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.

 

Introduction 

 

By winding number

 

35 kV class 3-phase two-winding power transformer

 

By tap-changing

 

35 kV class on-load tap-changing power transformer

 

 

35 kV class off-load tap-changing power transformer

 

 

Insulation Structure:


The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.

Tank:


The tank conservator tank type with radiator fins. 


Executed Standards:
IEC60076

 

 Protector

 

Check whether the alarm and trip point of the protector can work well, that is, whether there is an alarm in control room, whether the breakers has action, etc.
