2. Technical Feature

2.1 Transformer technology of CHINT Power T&D is based on model experiments, self-developed calculation software of leakage

flux, short circuit mechanical strength, on load losses etc, to realize overall optimization of electrical performance of transformer,

therefore low-cost and high-performed solutions could be provided to the customers.

2.2 The structure design is based on three-dimension finite element analysis software ,to do analysis on transformer iron c ore and

clamping pieces,which provides a guarantee to enhance mechanical strength,anti-short-circuit capacity and reduce noise.

Safety, fireproofing, non-polluting, direct operation on

the load center.

Strong mechanical strength, excellent insulation capacity,

low partial discharge ,strong radiation capability, high

reliability and long life.

Low loss, low noise, energy-saving.

High heat dispersion and strong serviceability , forced

air cooling can improve the operation of capacity.

4.1 Protection Enclosure

Protection enclosure can be made of general steel plate,stainless steel plate or aluminum alloy materials. For example, protection enc losure of IP20

can prevent solid object which is 12mm from entering, and this type is suitable for indoor installation. Protection enclosure of IP23 inherits the

characters of IP20 enclosure and can prevent water dropping at an angle within 60 to the vertical line from inflooding, as we ll wh ich is a dapt ed t o

outdoor installation.
