China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

HID ballasts Construction:
(A) High pressure sodium ballasts and metal halide ballasts silicon steel, enameled ring skeleton cover and base plate (shell), terminals.
(B) the role:
Coil: produce induced emf. Energized case, there is a certain resistance due coil will generate the power loss, the heat generated can make the inductive ballast temperature rise, easy to accelerate the aging of the ballast. In order to reduce the resistance of the coil, as far as possible with the import of high-purity electrolytic copper enameled wire.
Laminations: monolithic conductor is in a changing magnetic field, in the piece inside the conductor caused by induced current, commonly known as "vortex", which will cause the consumption of electrical energy, the temperature rise. In the inductive ballast, are used in order to enhance the strength of the magnetic induction of the core, but because of the presence of the eddy currents, must use a laminated iron core formed of thin laminations insulated from each other, rather than whole core, in order to reduce the eddy current the losses caused.
Bottom: fixed installation role.
Skeleton: fixed coil, chip, convenient wiring role.
Wiring terminals: from the junction the series magnetic ballast connected to the circuit.
