Product Overview:

The power industry often experiences fires caused by overheating of power cables and equipment, resulting in extensive cable burning and equipment damage that forces shutdowns, making it difficult to resume production in a short period of time and causing significant economic losses. Analyzing the accident, the direct causes of overheating and fire in electrical equipment are poor quality of cable intermediate joints, loose compression joints, excessive contact resistance, and long-term operation leading to overheating of cable heads and insulation burning. Therefore, wireless temperature monitoring of cable joint points is required.
