Abstract

The invention relates to a 10KV cable molded intermediate joint heating device; the structure is that the mold is connected with a temperature controller, and a plug is provided on the temperature controller; the mold is hollow, and a heating resistor is provided in the inner cavity of the mold. The outer surface of the heating resistor is covered with an insulating heat conducting layer. The invention is suitable for the production of 10kV cable molded intermediate joints. The electric heating method is used to replace the previous open flame heating method, which ensures the construction quality, reduces harmful gas emissions, and reasonably controls the temperature through temperature control equipment to save working time.

Description

technical field [0001] The invention relates to an electric heating device, in particular to a heating device for a 10KV cable molded intermediate joint; it is suitable for the molded heating part in the production of a 10KV molded cable intermediate joint, and can be used in high-risk places where blowtorches cannot be used for heating. Background technique [0002] In recent years, with the rapid development of cable grids in the province, almost all urban central areas have replaced overhead lines with cable grids. According to statistics in the first half of 2012, 38,632 10kV cables were used in the province, with a total length of 12,000.611 kilometers. The wide application of distribution cables also puts forward higher requirements for the construction and maintenance of cables. In the past, blowtorch heating was used to manufacture 10kV cable molded intermediate joints. This technology was difficult and time-consuming. Blowtorch heating is used, because it is manua...
