A method of manufacturing a cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. An electric power cable is provided having an exposed end including: a conductor core having an exposed portion and an unexposed portion; an insulation layer having an exposed portion and an unexposed portion covering the unexposed portion of conductor core; a semi-conductive shield layer having an exposed portion and an unexposed portion covering the unexposed portion of the insulation layer; a metal shield layer having an exposed portion and an unexposed portion covering the unexposed portion of the semi-conductive shield layer; and an outer protection layer covering the unexposed portion of the metal shield layer. A cold shrinkable termination is provided including: an insulation tube; a stress control glue; and, a support tube. The stress control glue is coated along a selected segment of an inner wall of the insulation tube. The insulation tube of the cold shrinkable termination is expanded on the support tube. The exposed end of the electric power cable is inserted into the support tube, and the support tube is removed from the insulation tube such that the insulation tube shrinks on the exposed end of the electric power cable. Thereby, the structure of the cold shrinkable termination is simplified and the cost thereof is reduced.

Method of manufacturing a cold shrinkable termination and assembly

A cold shrinkable terminal comprises a terminal body fixed to a cable joint disposed at an end of the cable and a composite void filling mastic. The cable joint includes a conductor core, an inner insulation layer disposed on the conductor core, and a conductive shielding layer disposed on the inner insulation layer. The composite void filling mastic covers an incision of the conductive shielding layer and includes a filling layer in contact with the cable joint and a separating layer disposed between the filling layer and the terminal body. The separating layer is made of a material different than the terminal body.

A street lamp controller comprises a switch configured to turn on and turn off a street lamp, a control module adapted to control the turning on and turning off of the switch, a detection module adapted to detect a data element relevant to operation of the street lamp, a data acquisition module connected to the detection module and adapted to acquire the data element detected by the detection module, and a wireless transmission module. The wireless transmission module communicates with a server and is adapted to transmit the data element acquired by the data acquisition module to the server and receive a control instruction sent from the server. The control module is adapted to communicate with the server via the wireless transmission module and is adapted to control the street lamp based on the control instruction received by the wireless transmission module.

A cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. When the cold shrinkable termination is mounted on the electric power cable, the stress control glue fills a gap between the electric power cable and the insulation tube so as to prevent local electric field concentration from occurring at an exposed end of the electric power cable. The stress control glue has a dielectric constant within a range of 5 to 100. In this cold shrinkable termination, a stress control glue with high dielectric constant is provided to optimize the electric-field distribution on an insulation surface of the electric power cable. Thereby, the structure of the cold shrinkable termination is simplified and the cost thereof is reduced. The cold shrinkable termination may be adapted to an electric power cable used to transmit voltage less than 26/35 kV.
