Abstract: The temperature rising early warning system comprises at least one thermosensitive release material, a sensor, a first warning unit, an analog digital converter, a microprocessor, a memory unit, a second warning unit, a transmission unit and a display unit. The thermosensitive release material comprises a thermosensitive material configured to release specific gases or particles at a critical temperature. The sensor is configured to detect the specific gases or the particle released by the thermosensitive release material and send out a signal.

Abstract: A filling material of power transmission bus bar, composed mainly of a silicone and an inorganic material, wherein weight ratio of said silicone and said inorganic material is between 1:0.1 and 1:9. As such, the resilience of the silicone can increase the buffering capability of said power transmission bus bar in facing pressure of strong winds; also stiffness of said inorganic material can increase the stability of said power transmission bus bar in a same situation. Said filling material of power transmission bus bar is able to protect metallic conduction element of said power transmission bus bar from getting in touch with moisture and dust, that may reduce its efficiency in transmitting power.
