12kV 1300A Dry Type Air Core Reactor Good Linearity Stable Reactance

12kV 1300A Dry-Type Air Core Reactor,Current Limiting Reactors

1. Overview of 12kV 1300A Dry-Type Air Core Reactor,Current Limiting Reactors

Compared with traditional oil immersion iron core reactor,dry-type air core reactors have advantages of light weight,good linearity,stable reactance,small loss ,low noise ,etc.The epoxy is adopted for envelopment,with high mechanical strength and super-high short-time current resistance ability .It is simple in structure and compact without oil.The star bracket and lead wire are welded by adopting the argon arc welding to greatly improve reliabiility of operation;Coverd with ultraviolet resistant paint on surface,it can be used for indoor and outdoor longtime running.Whereas the above-mentioned reason,dry-type air core reactors gradually supersede traditional oil immersion iron core reactors.

The Dry Tpe Air Core Series Reactors made By the us have got The multilayer winding shunt structure.every layer windingis
Shunt winded by the small bore aluminum lead and every layer’s leading-out are jointed on the two layer aluminum ally bus-bars.the whole reactor is enveloped by high temp solidified exopy fiberglass with the method of natural air cooling. The product is coated with the anti-aging,anti-UV,antifouling and hydrophobic dope. This type reactor has got the advantages of low-loss,high security.low-noise and convenient installation and maintenance. The product’s operation life reaches a length of thirty years.

2. Main features of 12kV 1300A Dry-Type Air Core Reactor,Current Limiting Reactors

• The reactor is enclosed by epoxy resin impregnated long glass fiber.The reactor is composed of several enclosures of coils.
• The coil is insulated by polyester film ,which has good capability of insulation.
• The reactor is painted with resisit aging ,ultraviolet-proof insulation coatings,and has fine performance operating outdoors.
• Between enclosure of coils,supports made of polyester glass fiber are used for axial heat radiator, this construction has abetter property of heat radiation.
• Dry-type semi-iron core reactor puts the iron core column in the hollow core of the hollow reactor, without enclosing the entire coil, and the iron core consumption is small;
• The core column is made of high-quality low-loss imported cold-rolled silicon steel sheet, which has high magnetic permeability, small coil diameter, low loss and low energy consumption;
