HV DC Contactors
Our HV DC Contactors Series
ZGVE Contactors are easy to assemble and quickly isolate equipment from live lines, ensuring safe circuit isolation during inspection and maintenance. The ceramic cavityis flled with hydrogen-based gas to ensure that thecontacts are not oxidized and can quickly cut off DC high voltage, which ceramic seal, no arcleakage risk. Their simple, durable design and low maintenance costs make them essential components in substations, industrial facilities, and a variety of power equipment applications.
Maximize Protection
Maximize Protection With Greater Precision and Improved Durability
We use MOVs supplied by LKD and GDTs from Vactech to ensure the stability and lightning protection effectiveness of our surge protectors.
We use metal lead pins with a thickness of 0.8mm and a width of 8mm, capable of handling high electrical potentials without easily breaking.
Our R&D team’s optimized low-temperature trip device and soldering process enhance the arc suppression and fire prevention capabilities of our surge protectors.
We use enhanced flame-retardant plastic casings to ensure the flame resistance of our SPDs. We select high-quality brass, red copper, and phosphor bronze components to ensure corrosion resistance during sea transportation
Only surge protectors that meet our testing standards are approved for shipment. All SPDs are certified by TUV, CB, and CE.
