earthing transformers, arc suppression coil are supported by the advanced packaged controlling system. The arc suppression coil developed by the company can automatically tune earthing line equipment, it is the intelligent synthesizer with automatically real-time tracking and compensating grid capacity and current and the single phase earthing optional line. It includes the earthing transformer, arc suppression coil, damping ...
Usually, the arc suppression coil supports the earthing transformer. It realize the fault protection when the grid single phase grounding through the computer control and load tap. Its aims are to blowout the arc and avoid the system power cut for the tripping operatiom.
The 66kv and below power supply system of China mainly applies neutrality point insulation way to supply power that is not earthing operation mode. And therefore in order to complete grounding protection it need to equip the earthing transformer to supply the neutrality point.

Epoxy cast dry-type earthing transformers is a new high-tech products of CNEKE transformers. The new products has the features of good electrical performance, strong overload ability, high mechanical strength, fire-retadant, moisture-proof, maintenance-free and low noise.
The winding applies the subsection multi stayed cable structure, and thus greatly reduce the working voltage of layer and internal, and is helpful to improve the product performance and service life.
