Performance Characteristic: 1. Safety. fireproofing, non-polluter, directiy used in load center.
2. High mechanical intension.
3. Low loss, low noise, obviously save energy, free from the maintenance
4. Strong ability of spreading hot and loading, and which they will be raised the capacity while forcing the breeze
5. Good function of defending moisture which make they suitable for in high degree of humidity and other bad environments.
6. Providing with the perfect temperature examination and the protection systems. Adopting the intelligence signal temperature controsystem, which can monitor and cruise back to show automatically the each work temperature of three-phase winding series; furthermore, they can start automatically and stop the breeze machine, and report to the police to jump.
7. Small size, light weight, little covering space, low expenses.

Structure Characteristic: ●The iron core is made of superior scion steel slice, structure isinclined joints fold type.
●Low-pressure coil that structure is foil type rounded by high-qualitycopper, the high-pressure coil that structure is layer type by the vacuum iron oxygen molded.

Technical Paraweters: Note: we only adjust the data for the product as following : when the weight add per 100kgs. the swith colloc ation will extends 750mm on the product sideDOmm on the face
we can provide the h-v change rage as: +4 x 2.5%
The data in table only for reference. we wouldn' t advice again if they are changed.
