Product Details
1 Application Area
Ultra-long distance heating cable LLHCL is a series of high-efficiency resistance heaters that are used for ultra-long length piping requiring temperature maintenance or freezing protection. Are used to minimize the number of power points, and a single power point can provide long-distance heating of the line.
Straying LLHCL long cables provide constant power per unit length of the circuit, preventing the voltage from decreasing as the circuit length increases. The solid metal shell increases mechanical strength, protects against external damage during laying and provides excellent fire performance compared to most cables.
Product applications: heating and heating of underwater, underground and elevated main pipelines, freezing protection and heating of pipelines in urban engineering corridors and underwater tunnels. Anti-freezing of main fire extinguishing pipelines, etc.
2. Product installation diagram
1. Product installation diagram (1) When the pipeline is pre-manufactured and insulated, three protective grooves are fixed on the pipeline and then foamed and manufactured by the factory; (2) When the pipes are connected in place, make sure, That the protective grooves are aligned to provide a displacement of lla 2mm to protect the heating cable sheath from cutting when the heating cable is pulled through; (3) The length of the protective groove side is 2;
