Abstract: The present invention provides an inlet funnel (100) for cable terminal, which comprises a funnel body part (10) and a fixation part (20). The funnel body part (10) has one end with a smaller opening and the other end with a larger opening, said funnel body (10) having a gradually increasing diameter (D) from said one end with the smaller opening to said other end with the larger opening, and the funnel body (10) is suitably to be installed over an electrical cable (C). The fixation part (20) is provided at said other end with the larger opening of said funnel body part (10) and adapted for the attachment of said inlet funnel (100). The inlet funnel (100) further comprises a pretreated mounting part (30) extending from said one end side with the smaller opening towards said the other end side with the larger opening. Accordingly, the inlet funnel for cable terminal according to the present invention may reduce workload, save time, and simplify the mounting process.

Abstract: A temperature-sensing apparatus for sensing the temperature of an electrical conductor (31), comprising a sensor frame (210) including a frame body (2101) and a channel (2102) adapted to accommodate the electrical conductor (31). At least a portion of a temperature sensor is received in a chamber (2103) of the sensor frame (210). At least a portion of a thermal contact member is disposed between the electrical conductor (31) and the temperature sensor and configured to enhance thermal-contact therebetween. At least a portion of the thermal contact member is radially pressable against the electrical conductor (31).

Abstract: Systems and methods for directly sensing, measuring, or monitoring the temperature of an electrical conductor (31) of a power cable (10), are provided. A surface acoustic wave (SAW) temperature sensor (20) is used that includes a substrate (20S) with a transducer (20T) disposed thereon. The transducer (20T) conducts conversion between an electromagnetic signal and a SAW signal that propagates on the substrate (20S). At least a portion of the substrate (20S) is disposed in thermal contact with the electrical conductor (31) such that the SAW signal varies with the temperature of the electrical conductor (31).
