Single Phase CSP and CP Transformers-Self- Protected Transformers

Single Phase CSP and CP Transformers

The completely self -protected (CSP) units are rated 5-167 kVA. CSP transformers have direct connected primary arresters, secondary breakers, and internal primary voltage fuses. This eliminates the need for separately mounted protective devices and installation economy results.

• Secondary breaker operating handle with emergency overload reset and overload signal light.
• 18 months standard warranty
• After sales maintenance and spare parts service

CSP is cheaper:

Conventional transformers with external cutout fuse and lighting arresters might first appear to be a less expensive, but when you add up the substantial extra costs of cutout fuses, longer installation time, increased outage down time, and time lost repairing and replacing damaged equipment, and so on, conventional transformers just cannot compete with CSP!

CSP is safer:

Completely self-protected transformers are safer by design. Along with internal installation that offers superior protection against animal intrusion, CSP offer the solutions to common problems.
