Designation
iUN-panel units are identified by a code including:
- an indication of the function, i.e. the electrical diagram code: IM, QM, DM1, CM, DM2, etc.
- the rated current: 400 - 630 - 1250 A;
- the rated voltage: 7.2 - 12 - 17.5 - 24 kV;
- the maximum short-time withstand current values: 12.5 - 16 - 20 - 25 kA.1 s;
- the color is of RAL 9002 type (frosted satin white).
Example for a unit designated: IM 400 - 24 - 12.5
- IM indicates an "incoming" or "outgoing" unit;
- 400 indicates the rated current is 400 A;
- 24 indicates the rated voltage is 24 kV;
- 12.5 indicates the short-time withstand current is 12.5 kA.1 s.
The hereunder values are for working temperatures from -5°C up to +40°C and for a setting up at an altitude below 1000 m.
Internal arc withstand:
- standard:12.5 kA. 0.7 s;
- enhanced:16 kA. 1 s.
Protection index:
- units: IP2XC (IP3X consult us);
- between compartments: IP2x.
Electro-magnetic compatibility:
- relays: 4 kV withstand capacity, as per recommendation IEC 60801.4;
- compartments:
- electrical field:
Temperatures:
The cubicles must be stored in a dry area freefrom dust and with limited temperature variations.
- for stocking: from -40°C to +70°C,
- for working: from -5°C to +40°C,
- other temperatures, consult us.

Our Advantages
(1). Energy conservation: Farady voltage regulating type capacitors will change the output reactive power by regulating voltage on capacitors, so that the reactive power can be adjusted smoothly. Comparing with other method, it can ensure the capacitors in best condition, the energy saving effect is much better
(2). Low cost:If the old power transformer substation need to reform, only need to add a voltage regulator between the circuit breaker and capacitors, the original circuit breakers, reactors, capacitors can be reuse, greatly reduce the cost of transformation
(3). Maintance Free:When traditional circuit breaker and contactor switching, switching devices and capacitors often damaged because of the above problems, result in high maintenance costs, using Farady devices, automatic control reactive power output, there is no potential risks of other equipments, greatly reducing maintenance and staff costs in power transformer substation
