1. It can be directly installed at the load center, which is free
of maintenance and install conveniently, therefore it has low
comprehensive running cost.
2. With high moisture resistance, it runs normally at the moisture
and can be put into operation without being dried after outage,
with low loss and local discharge capacity.
3. It has small noise, strong short circuit resistance and
excellent environmental performance, and can run under severe
4. It is safe, fire-retardant, fireproof and environment-friendly.
The hoisting, tooling and testing equipment is complete. Pearl
Electric has passed the ISO9001-2015 international standard quality
management system certification. Adopting advanced technology and
high quality raw material, with first class equipment and strict
processing, SC-series resin casting dry type transformer. All
performance indicators of the products have reached the relevant
national standards and international standards.
Pearl Electric's products are universally used in different
industries, involving power plants, chemicals, construction,
