3. Service Condition
Ambient Temperature: -40oC~+40oC
Altitude: less than 1000m(above 1000m, technical conditions should be separatedly negotiated by both sides)
4. System Conditions
System Neutral Earthing Method: non-effectively earthed
5. Structure Feature
- It is organic insulation type product. The external insualtion is silicone rubber petticoat.
- Electric field evnely distributed, partial discharge small amount and stable, small dielectric loss.
- The current ratio can be changed easily by changing the connection method in shielding enclosure to facilitate the realization to series or parallel connection.
- The grading cover which is aluminum alloy casting formed and the cabinet which is stainless steel plate drawing formed, use DACRAL(Zinc/Chromate coatings) for resistance to corrosion, which gives a high degree of corrosion resistance.
- All parts, such as stainless bolts, nameplate are rust-free all the time.
- The product has no oil, no ceramic, no gas.
- Barely need for maintenance. Just need to measure once capacitance and dielectric loss factor every 2~3 years.
