Farady Electric manufacture a complete range of overhead and pad mounted type distribution transformers, including single phase and three phase pole mounted conventional, complete self-protection (CSP),step down transformer, pad mounted & compact substation transformer, step voltage regulator etc, we always designed with increased margins of safety and reliability ,and meet the following standard:
IEC60076,ANSI/IEEEC57.12.00, C57.12.20, C57.12.90, BS171, SABS 780 etc
Our completely self-protected distribution transformer is used to offer electricity to facilitate lighting system, agricultural production and industrial factory in rural places, remote areas and scattered villages, and it is also applicable for pole-mounted distribution lines for railways and urban power grids.
Advantage
The completely self-protected distribution transformer could reduce the length of low voltage distribution lines and improve power supply quality. The wound core is proven to be an energy efficient design, and the pole-mounted method saves both space and money. With the help of this product, the low voltage power supply radius is cut down, and the line loss is 60% lower at least.
Service condition

- f) No frequent violent shake
Note: * Beyond those services condition should enquiry to manufacturer technical dept during order
conventional transformer with external cutout fuse and lighting arrester might first appear to be a less expensive choice,but when you add up the substantial extra cost of cutout fuse,longer installation time,increased outaga downtiime,and time lost repairing,replacing damage equipment,and so on,convential transformer just can’t compete with CSP

Lightning arrester is pre-installed in the CSP and included in cost |
Completely self-protection transformers are safer by design.Along with internal installation that offers superior protection against animal instrusion,CSP offer those solution to common problems
System problem |
CSP |
Conventional |
Low voltage fault |
A low voltage breaker senser the
fault and trip,protecting the transformer
CSP is the only solution to the secondary
Fault condition
|
A cutout fuse may not react fast
Enough to prevent a transformer
Failure
|
Lightning |
Close proximately and line side placement
Of surge arrester protects against suge and eliminate outage
|
A cutout fuse installed a distance from the transformer on the line side may delay out
Age but still allow damage to the transformer
|
Overloaded transformer |
A low voltage breaker trip and protects the transformer.signal light and emergency overload switch allows quick indentification of problem and fast power restoration |
A cutout fuse will probably not respond fast enough.resulting in transformer failure |
Service restoration |
simply close the breaker,no power indicates a transformer fault,no eventful failure would happen |
refuse and close in cutout,a secondary fault may blow the fuse again.also an internal transformer fault could lead to a eventful failure blown over |
Early warning |
if a reset breaker holds,the transformer can be watched for future problems,or scheduled for change-out.signal light also provides early warning of an overload |
No early warning,cutout will most likely not respond fast enough to a failed transformer |
CSP design provide maximum protection against transformer failure and disruptive outages.it also protects you from extra cost of more complicated installtion,unnecessary equipment damage and power dowtime.With US import low voltage breaker for CSP transformer system you get CHEAPER,SAFER,PROTECTION!
