CSP Type Transformer

CSP is a protection system for distribution transformers. The CSP protection system protects from the lighting, secondary faults, severe overloads, and provides visual warning of the existence of uneconomical loading conditions. The CSP design provides maximum protection against transformer failure and disruptive outages. It also protects you from the extra costs of more complicated installation, unnecessary equipment and power downtime.

Features and benefits
• High voltage surge arrester
• Primary protective link.
• Secondary circuit breaker
• 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.

Application
Urban and rural electrification
Public utilities
Highly polluted and hazardous conditions

FAQ

Listed below are answers to our most commonly asked questions. Don't see your question?Contact our customer service team. We would be glad to assist you.

Can a transformer be used outdoors?

Yes, many transformers are designed for outdoor use, but they require waterproofing, dustproofing, and protective enclosures to withstand rain, dust, and temperature changes.

Is transformer noise normal?

A slight humming sound during operation is normal, caused by magnetization of the core and windings. However, if the noise is unusually loud or irregular, inspection is required.

What causes a transformer to overheat?

Common causes of transformer overheating include overloading, inadequate cooling, winding short circuits, or insulation aging. Prolonged overheating can shorten lifespan or cause failure.

How often should a transformer be maintained?

It is generally recommended to have a full inspection once a year, including insulation, cables, cooling systems, and oil quality tests to ensure safety and efficiency.

Can a transformer run continuously?

Yes, transformers are designed for long-term stable operation. As long as they run within rated voltage, load, and temperature limits, they can operate safely and continuously.

What is the main function of a transformer?

The main function of a transformer is to change voltage levels. It can step up voltage for long-distance transmission or step down voltage for safe use in equipment and households.
