1. Non - intrusive equipotential installation: Adopting the equipotential design, it is directly installed on the surface of the strain clamp. There is no need for power outage during construction, which does not affect the normal operation of the line. At the same time, it avoids the electromagnetic interference of the line and ensures the temperature measurement accuracy.
2. Self - powered and maintenance - free design: Relying on the electric field energy collection technology and combined with the comprehensive power supply of the battery, there is no need for an external power supply. It is suitable for the long - term operation of outdoor transmission lines and significantly reduces the operation and maintenance costs.
3. Graded alarm and data security: It supports three - level temperature threshold alarm. The data is encrypted for transmission and accessed to the intranet platform, taking into account the needs of hidden danger early warning and data security.
