TBBL High Voltage 6kV, 10kV Power System Filter Reactive Compensation Package

Product overview

TBBL high voltage filter reactive compensation package is used for 6~ 35kV power system, mainly installed in power, steel, metallurgy, chemical, coal mine, light industry, building materials and harmonic current, absorb the harmonic current generated by nearby harmonic source, inhibit harmonic and eliminate electric harmonic "pollution".

TBBL device is connected in parallel. In addition to filtering, it also provides reactive power to the system and improves the power factor for reactive compensation.

Use environmental conditions

• Installation environment: outdoor or indoor.
• Elevation: not more than 1,000 meters.
• Environmental temperature: -40℃ ~ + 45℃.
• Relative humidity: with a monthly average of no more than 85%.
• Anti-pollution ability: external insulation creep ratio distance is not less than 25mm/kV(relative to the highest operating voltage of the system).The climbing power ratio distance should be appropriately increased for the heavy pollution area.
