Overview
Our company has developed an electrical contact temperature online monitoring device to promptly detect temperature rise issues in electrical equipment junctions caused by factors such as material aging, poor contact, and overcurrent. This product features low power consumption design, wireless temperature measurement technology, and boasts complete isolation, easy installation, strong anti-interference capability, and reliable operation, effectively addressing temperature measurement challenges under high-voltage conditions.
Application: Temperature monitoring for equipment such as high-voltage switchgear contacts and terminals, switch disconnectors, ring main unit cable heads, dry-type transformers, and low-voltage high-current cabinets.
