Feature""
1.Coil adopts epoxy resin pouring with flame resistance property reaching standard V0. It enjoys characteristics of flame resistance, non-dust accumulation, good moisture resistance, good chemical resistance, high mechanical strength and strong short-circuit resistance capacity.
2.High voltage coil with segmented layer type structure, low voltage coil with foil type winding, plus advanced pouring process, can greatly reduce voltage between layers and partial discharge, and increase sudden short-circuit resistant capability.
3.Air duct of low voltage coil is cellular, evenly distributed along the circumference. Heat dissipation of coil is even, with good heat dissipation effect. Meanwhile, expand the duct between low voltage coil to iron core, and high voltage coil to low voltage coil, which is also good for heat dissipation.
4.Conduct vacuum pouring on high voltage and low voltage coils, and adopt high voltage standing process after pouring to make the injected resin more compact, which can completely eliminate residual bubbles in the coils to ensure partial discharge of each product is lower than 5pC.
