Why Choose ZHIMING's High Voltage Electrical Reactor?
Dry-Type Iron-Core Design for High Voltage Systems
The CKSC Series High Voltage Electrical Reactor employs a dry-type iron-core construction rated for power systems up to 63kV, eliminating the maintenance burden of oil-filled reactors while delivering stable inductance across the operating range. With LI75AC35 insulation (75kV lightning impulse / 35kV power frequency withstand), it meets the dielectric demands of medium and high voltage substation environments.
Extreme Environmental Adaptability
Operating reliably from -40°C to +45°C ambient temperature and rated for seismic intensity up to magnitude 8, this reactor is engineered for the harshest deployment conditions — from arctic substations to tropical industrial plants. It tolerates humidity up to 90% monthly average and wind speeds up to 35 m/s in outdoor configurations.
Precise Short-Circuit Current Limiting
When a downstream fault occurs, the series-connected CKSC reactor limits short-circuit current magnitude, reducing mechanical and thermal stress on transformers, switchgear, and cables. Reactance tolerance is tightly controlled: within -5% at 1.8× rated current, 0% to +5% at rated power frequency current, and ±2% between individual phases and the three-phase average.
Ex-Certified for Hazardous Locations
The CKSC Series is suitable for environments requiring explosion-proof certification, including petroleum refineries, chemical plants, and mining operations. Its dry-type design removes flammable insulating oil from the equation, while the iron-core construction provides inherent electromagnetic shielding — making it a safe choice for installations with constrained space, strong EMI, or elevated fire safety requirements.
PERTANYAAN YANG SERING DIAJUKAN
What voltage level does the CKSC High Voltage Electrical Reactor support?
The CKSC Series is designed for power systems rated 0–63kV. It is series-connected within the system to provide reactive compensation, harmonic filtering, and short-circuit current limiting across a broad range of medium and high voltage applications.
Where are these High Voltage Electrical Reactors typically installed?
CKSC reactors are deployed in power utility substations, electric railway traction substations, and industrial facilities in metallurgy, chemicals, and petroleum sectors. They are suitable for both outdoor and indoor installation, including environments requiring explosion-proof certification.
What are the noise and temperature rise limits?
Noise is limited to ≤55dB for units under 600 kVA and ≤58dB for units between 600–1,200 kVA, measured at standard distance. Maximum temperature rise under rated conditions is 90K, supported by the dry-type iron-core design which dissipates heat through natural air convection.
How does the CKSC Series limit short-circuit currents?
When series-connected in the power system, the reactor’s inductance provides additional impedance that restricts the magnitude of fault currents during short-circuit events. Reactance values are controlled to tight tolerances: maximum -5% deviation at 1.8× rated current, and 0% to +5% at rated power frequency current, with per-phase balance within ±2% of the three-phase mean.
Can I order a CKSC reactor with custom specifications?
Yes. The standard dimension and weight table covers 20 models from CKSC-6/10-6 (180kg) to CKSC-180/10-6 (500kg), but ZHIMING can design and produce reactors to meet non-standard voltage ratings, kVA capacities, reactance values, dimensions, and environmental requirements. Contact the manufacturer with your specifications.
