Packaging & Shipping

1.Compact type
      This type of devices install all electrical components in the cabinet that required, cabinet made of galvanized steel or stainless steel, the voltage is 3 5kV and below, capacitance below 4000kvar will use such structure. This type of structure is orderly, the installation and the maintenance are convenient, the occupied area is small, and the structure is suitable for the interior installation of a new power transformer substation. 

2 .  Outdoor type
      This install type with a fence around the equipment enclosure ,occupy an area of slightly larger, but the maintenance is very convenient, for in indoor and outdoor use, especially suitable for old power transformer reforming.

Our Advantages

    The traditional way of reactive power compensation is changing the quantity of capacitors to adjust output reactive power, change method is usually switch or contactor, will result in following hazards:
1. The conventional reactive power compensation method has a large compensation capacity and the adjustment is not flexible, it will lead to the compensation is not suitable , often appear over and not enough.
2. The capacitor switching can cause over-voltage and inrush current, and it will seriously affect and reduce the service life of the switch. 
3. When the capacitor is switched on, as the capacitor will charged and discharged, when it need to switch on again, which affects the speed of the switching..
       According to the above problems, our company developed the FLYK type reactive power compensation device, has the following 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 
(4) Quality Assurances
We have a strictly quality control process from the raw material to finished products. Advanced testing lab to make sure products quality and improve our creative ability. Quality and Safety is the soul of our products.
(5) Excellent Services  
Many years of manufacturing experience and rich export business help us to establish a well-trained sales service team for all customers.
(6) Fast Deliveries
