■OPERATING ENVIRONMENT 

  1. Altitude in service not exceeding 2000m*

2. Ambient temperature is between the range of -40~+45℃ *

3. Relative humidity of environment is not higher than 85 %( in 20±5℃)

4. Pollution class Ⅳ(Leakage distance is larger than 3.1cm/kV)

5. There is no fierce vibrating, noxious gas, the steam, and conductive and explosive dust particle in the installation sites.

6. Installation site is well-ventilated if indoor.

*Proposal should be proposed before ordering when surpassing this value.

■GENERAL TECHNICAL CHARACTERISTICS 

1. Capacity deviation -3~+5%.

2. For AC rated voltage the loss angle tangent value of capacitors is no more than 0.03% at 20℃.

3. Capacitors permit voltage up to 1.05Un for a long time in the power frequency stable state. Under the condition of 1.1Un

power frequency stable state, capacitors should not be used for more than 8 hours every 24 hours.

4. It is permitted capacitors run on the effective value 1.3In stable state, created by overvoltage and the higher harmonic, for a long time. For capacitors with the largest positive deviation capacity, the allowable overcurrent should not exceed 1.43In on the effective value.

5.This product complies with the standard of GB/T11024.1-2010 and IEC60871-1:2005 Shunt Capacitors for AC Power System having a rated voltage above 1000V---part 1:General and DL/T840-2003 Technical Specification of High Voltage Shunt Capacitor.

■STRUCTURE AND CHARACTERISTICS OF THE PRODUCTS 

1. The capacitor is mainly composed of a case, high strength of the crimping bushing and a core.

2. The case, made of good quality stainless steel molding, is made by argon arc welding to ensure that the product has a good tightness and high explosion stability. Can run well in low temperature environment.

4. Elements are made up of high-quality polypropylene film and ultra-thin aluminum foil. Folding and convex aluminum foil structure improves the plate edge effect. So the partial discharge characteristics of capacitors are improved.

5.The product is equipped with glass glaze film discharge resistor which is very reliable and can reduce the voltage from the initial peak voltage of √2Un to below 75V in 10 minutes after the power is cut off.

6. The shunt capacitor with built-in fuse which is arranged between the elements can ensure the intact elements operate normally when isolating the faulty elements effectively at the same time. Then products can be with higher reliability.

7. The elements of products are rolled in the ultra-clean state. Cluster pumping single note drip impregnating technology is used for impregnation process which makes the products have the characteristics of low loss, low magnitude of partial discharge and long service life.
