Abstract

The invention provides an armored heat-tracing cable junction box, and belongs to the technical field of cable equipment. The junction box comprises an internal fixed part and a protection housing. The inner wall of the protection housing is smooth, and the exterior of the internal fixed part is uniformly provided with a metal line groove which passes through the exterior of the internal fixed part. The metal line groove is provided with a fixed groove, and the depth of the fixed groove is greater than the depth of the metal lien groove. The protection housing is located at the exterior of the internal fixed part, and the protection housing comprises a first protection housing and a second protection housing. The first and second protection housings are in threaded connection, and the end parts of the first and second protection housings are provided with sealing rings. The junction box provided by the invention is simple in structure, is convenient to use, is reasonable in design, can enable the same type of armored wires and cables to be connected, is firm in connection, is good in sealing performance, and can solve a problem that an armored heat-tracing cable is not long enough.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to an armored heat tracing cable junction box. Background technique [0002] Usually, in the recovery process of oilfield viscous condensate oil, due to the special components such as bitumen and wax in the crude oil, the characteristics of high viscosity and poor fluidity are formed, coupled with the interference of the cold climate and frozen soil in the north, in the mining and production In the process, when the crude oil reaches the gathering and transportation pump station from the oil layer through the oil pipeline and the oil pipeline, the temperature of the crude oil is lower than the critical flow temperature due to heat loss. This will lead to the precipitation and deposition of wax, the sudden increase of viscosity, the increase of flow pressure and the decrease of flow pressure, which will lead to the failure of smooth mining or very difficult recovery.
