CKSG Iron Core Series Filter Reactor (F / H Class Insulation)
// Harmonic Suppression & Protection
Protecting Capacitors & Motors from Harmonic Destruction
Non-linear industrial loads (such as variable frequency drives, arc furnaces, and rectifiers) inject severe harmonic currents into the power network. AIKey reactors prevent parallel resonance, clamp switching surges, and extend motor insulation lifespan.
- ✓ High Magnetic Linearity (≥ 1.8x – 2.0x In): Magnetic cores are segmented into multiple air gaps bonded by high-temperature epoxy, preventing core saturation during heavy harmonic overloads.
- ✓ Inverter Line Protection (ACL & OCL): ACL dampens power grid voltage spikes to protect VFD rectifiers; OCL mitigates high dv/dt reflections to safeguard motor winding insulation over cable runs > 50 meters.
- ✓ Class H (180°C) VPI Vacuum Impregnation: Ultra-low acoustic noise (≤ 50dB at 1 meter), high mechanical vibration resistance, and superior thermal withstand.
- ✓ MNS 3.0 / GGD Low-Voltage Switchgear: Modular withdrawable & fixed power distribution boards, form 4b separation, rated current up to 6300A, short-circuit withstand up to 100kA.
