Strict testing


Temperature rise test is applied to the first energizing transformer products of same capacity and structure.


 Reliable temperature controller device


Temperature controller provides real-time temperature rise monitoring for energizing transformer, which plays a very important role in the safe operation of the transformer.

Pearl Electric Co., LTD selected supplier the largest manufacturer of dry-type transformer temperature controller in China, Fujian Lide, with strong technical strength, whose product is widely used in many national key projects.


The product strengths are listed as follows:

Reasonable structure design, with separated circuit for control and display to avoid interference.


Trip-temperature is outputted after repeated judgment being confirmed, and its software is interlocked with over-temperature alarm;


Trip circuit has resistance-capacitance filtering, interlocked with over-temperature alarm hardware.


Three-wire system sensing bus and reasonable plug design.

Improved control strategy with temperature compensation function.

Good resistance to electromagnetic interference, certificated by domestic testing authority.


Features & Advantages


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity. 45° mitring and 5-steps overlapping structure is adopted for the core design, thus to greatly reduce no-load loss and no-load current.

HV winding

HV winding is manufactured with high quality copper wire, reinforced with glass fiber and being casted with epoxy resin at vacuum state with pressure, having the resin fully impregnated into the coils in the most professional imported equipment. 

LV Winding

The winding conductor shall be made of limb wide copper or aluminium foil where the width
of the foil shall be equal to the final height of the winding. 
The foil winding shall be protected and reinforced using glass-fiber fabrics or quartz powder.



Cooling Channels

Cooling channels if any, shall be arranged in a vertical manner and all coils shall have an even
and smooth surface to minimize any dust accumulation as well as to give the maximum cooling

Dynamic Short Circuit Strength

All windings shall be designed and constructed as self-supporting to withstand without damage
the dynamic effects of external short circuit conditions, without taking into account the
contribution to the mechanical strength from insulating structure and other adjacent windings.

Executed standards
IEC60076-11, DIN42523
