what uimp means

uimp means rated impulse withstand voltage. (Recommended Learning: PHPSTORM )

The rated impact tolerance voltage UIMP. Under the specified conditions, the electrical appliances can tolerate and not penetrate the specified shape and extreme The impulse voltage peak value is related to the electrical clearance.

The Uimp of the switching appliance should be equal to or greater than the transient overvoltage value that may occur in the line where the appliance is located.

Circuit breaker technology design

The incoming cabinet, feeder cabinet and bus tie cabinet using circuit breaker technology, whether it is a withdrawable structure or a fixed installation type, All are equipped with 3WL/3WT type circuit breakers.

Because most electrical equipment is connected behind this type of switch cabinet, it has special significance from the perspective of long-term operational reliability and personal safety of the switch equipment. SIVACON implements these requirements using components from circuit breaker technology.

Fixed technical design

The power distribution cabinet for the cable feed circuit adopts a fixed installation structure. According to user requirements, it can be equipped with circuit breakers or fuses. Isolating switch. This type of power distribution cabinet is mainly used in situations where replacement is not required under working conditions or where brief power outages are allowed. In this case, SIVACON fixed installation technology shows its high economy, safety and adaptability.

Reactive power compensation

The control cabinet for centralized reactive power compensation can reduce the load on transformers and cables, reduce transmission losses, and save electricity costs. Depending on the structure of the electrical equipment, the control cabinet can be equipped with non-choke or choke capacitor components.

Plug-in design

The plug-in switch cabinet equipped with motor circuit and cable feed circuit is a more economical alternative to the withdrawable design. Through the plug on the incoming line side, the unit can be quickly replaced without powering off the entire switch cabinet.

Withdrawable design

The withdrawable switch cabinet equipped with motor circuit and cable feed circuit has the best safety and applicability, and provides a higher Ease of operation. The guided pull-out mechanism allows for quick and easy replacement and adjustment. Each module can thus be eg augmented or transformed, even the compartments can be transformed during operation. SIVACON's withdrawable design provides high applicability
