Jiahong ESF series heating cable can be normally used for pipe freeze protection and temperature maintaince, especially it is the best and economic solution for longline pipe which the length exceeded the maximum circuit length of self-regulating or parallel constant power output. Single-core, twin-core and triple-core which are named as 1ESF, 2ESF and 3ESF are three types of series heating cable, as well as different resistance spec, so the heating cable can be suitable for different voltage level (Shown in certifification) and electrial connection, as well as to the heat tracing requirement for different type or length of pipeline and vessel.
The core is resistive heating conductor, and high temperature fluoropolymer inner insulation layer, tinned copper braid, high temperature fluoropolymer are to be added to form a complete structure of ESF heating cable, in addition there is high temperature fluoropolymer composition layer between braid and conductor in twin-core (2ESF) and triple-core (3ESF) structure.
ESF heating cable is certifified by IECEx, ATEX, NEPSI China and EAC Russia, including explosion-proof application, which can be used in the explosion area and ordinary safety area.
Simple installation and stable power output of unit length.
Different electrial power connection to achieve the heat tracing requirement in most economic and optimization.
It has a complete series of accessory, including standard power box, splice/tee connection box and end seal box etc, which can ensure the long service life of the product
