2. ++++General
Farady Electric manufacture a complete range of single-phase and three phase
overhead distribution transformers, including conventional & complete self-protection
(CSP) type transformer, we always designed with increased margins of safety and
reliablity,and meet the following standard:
IEC60076,ANSI/IEEEC57.12.00, C57.12.20, C57.12.90, BS171, SABS 780 etc
++++Application
Our single phase overhead 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.
++++Advantage:
The conventional distribution transformer makes use of highly efficient and
energy saving wound core, and our product is mounted on the pole, thereby
cutting down the installation size, construction cost and low-voltage power
supply radius. As a result, the low voltage line loss is reduced by as much as
60% or more, and the power supply quality is enhanced. Moreover, this device is
featured by excellent overload capability, convenient maintenance, continuous
and reliable working, etc.
