RockWell’s goal is to offer products that reduce the overall cost of ownership to customers in terms of time, labor and materials.
Complete self-protected technology for high performance distribution transformers
CSP is a protection system for distribution transformers. The CSP protection system protects the transformer from lightning, secondary faults, severe overloads and provides visual warning of abnormal loading conditions.CSP technology allows transformer manufactures to build high performance distribution transformers which mitigate the operation and maintenance problems associated with conventional transformers.
CSP design provides maximum protection against transformer failure and disruptive outages. It also protects you from extra costs of more complicated installation, unnecessary equipment and power downtime.
RockWell CSP protection system
Rockwell transformer CO.,LTD manufactures several components, in order to create the CSP transformer. These components when applied to the transformer during its manufacturing process, provide multiple layers of protection.
High voltage fuse
Acts as over current protection by isolating the faulty transformer from the network. it is mounted inside of the transformer and it is connected between the incoming high voltage lead from the bushing and the high voltage line lead from the transformer primary winding.
Low voltage (secondary) circuit breaker
Provides secondary fault and overload protection. the circuit breaker is mounted inside of the transformer and it is connected between the secondary winding and secondary bushing, such that the current flows through the circuit breaker.
Provides visual indication of abnormal loading conditions. the signal light is electrically connected to the signal light sensing circuit within the transformer.
The low voltage circuit breaker is the central component of CSP technology. It is this circuit breaker which provides the entire over current protection to the transformer. Circuit breaker protects the transformer in the following scenarios:
To increase the longevity of the transformer the circuit breaker will trip once the oil in the transformer reaches a pre-determined temperature level.
Similar to thermal protection, the circuit breaker will protect the transformer from damaging overloading conditions for a sustained period of time.
Secondary fault (short circuit):
The circuit breaker will respond to secondary faults external to the transformer by tripping open, and in most cases, this action will prevent any thermal damage occurring to the transformer.
RockWell circuit breaker advantages
Conforms to IEC standards IEC-60947-2 specifications.
High quality components
Available in 1-Pole,2-Pole and 3-Pole variations for single phase and three phase transformer. Current rating up to 270Amps.
Thermal protection settings customized as per customer requirements.
Signal light to provide early warning of overload/high oil temperatures.
Operating handle allows quick reset.
Magnetic trip element increases the opening speed of the circuit breaker under high fault current conditions. this increased opening speed permits the circuit breaker to interrupt larger values of fault currents.
Emergency control allows the power utility to immediately restore service in an emergency by closing the circuit breaker even when the preset overloading limit is reached.
Breaker on bracket (BOB)
Breaker on Bracket design allows simple and fast installation of the circuit breaker. significantly reduces any issues borne out of incorrect installation of the circuit breaker.
1.The payment term: We accept TT,30% deposit and 70% balance against copy of BL.
2.The delivery time: Usually it will take about 15-20 days.
3.The standard of package: Usually use strong plywood case for protection.
4.The material of transformer: We have two types, one is with copper and another one is with aluminum. It depends on your requirement. In fact, those two have difference if normal work well. Only except the long life. Copper is better and also higher price.
5.The logo: If you have good quantity, it absolute no problem to do OEM.
6.Our market: our products are popular in Indonesia, Philippines, Russia, USA, Middle East and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefit from our cooperation..
