.Energy-saving, automatically varies its power output in response to pipe temperature changes.

.Easy installation, it can be cut to any required length.

.Lower installed cost than steam tracing, less maintenance expense and less downtime.

.The self-regulating effect allows the cable to be overlapped without creating hot spots or burnout.

.Approved for use in non-hazardous, hazardous and corrosive environments.

.Jiahong provides full range of controls and accessories.


The output regulation of SLL series heating cables is carried out automatically along the entire length of heating tape according to the prevailing ambient temperature.Its self-limiting characteristics improve safety and reliability. It will not overheat or burnout, even when overlapped upon itself.With optional outerjacket the heating cable is resistant to watery and inorganic chemicals and protect against abrasion and impact damage.

SLL is suitable for use in explosion-hazardous areas up to a maximally admissible work-piece temperature of +65℃.

Jiahong provides termination, power connection, splice,tee and end seal kit will reduce installation time and require no special skills or tools.


SLL self-regulating heating cable is a parallel circuit electric heater strip. It’s approved for residential and commercial metal and plastic pipe freeze protection and roof and gutter de-icing applications.

It is ideal for use in maintaining fluid flow under low ambient. Freeze protection

and low watt density process temperature systems such as pipelines, fire protection, process water, dust suppression systems, hot water and structure anti-icing are typical applications for this product. A flame-retardant,

UV-resistant jacket protects the braiding against humidity and offers additional protection against mechanical stress.
