Zhejiang Farady Electric Co., Ltd.
ISO9001&ISO14001 certificated enterprise

2. ++++General
Farady Electric is an ISO9001-2008 certified company that has been manufacturing
exceptional distribution and power transformer for last 10 years,one of the reasons for
our sucess over the last decade has been a rigid quality system supported by our
quality assurance programs and ongoing research and development, all design
undergo complete type testing and routine testing, as per the applicable standards
Farady Electric's single phase pad mounted distribution transformers provide a
reliable and affordable solution for clients who need to reduce their overall operating
costs. they are low-profile, compartment-type tranformers,which are generally used
for step-down purposes from an undergroud primary cable supply suitable for
mounting outdoors on pads without additional protective enclosures,and meet the
following standard:
IEC60076,ANSI/IEEEC57.12.00, C57.12.20,C57.12.38, C57.12.90, BS171, SABS
780 etc
++++Application
Our single phase and three phase pad-mounted distribution transformer is
commonly used in
various places including rural areas, remote regions and scattered villages to
provide high quality power supply for daily lighting, agricultural production
and industrial plants. Aside from these, it is also suitable for the energy
saving projects for railway and urban grid.
