Low-temperature self-regulating heating cable RIZUR-SGL-N

RIZUR-SGL-N is a low-temperature self-regulating heating cable used in various branches of the industry, including those with explosion-hazardous facilities, for maintaining set temperature and equipment protection against freezing. RIZUR-SGL-N is designed for heating vessels, tanks, and pipelines. This design variant is manufactured for pipes of small diameter. Thermoresistance of the cable is up to 65/85°C (65 - max. temperature, 85 - max. temperature with no load - 100 hours total).


Intended use and application area

RIZUR-SGL-N reacts to changes in both ambient and surface temperature and automatically controls heat release. It's used for temperature maintenance in reservoirs, tanks, and pipelines of small diameter, as well as for equipment protection against freezing, ice formation, and other impacts of low temperatures. Self-regulating heating cable is used at facilities in various branches of the industry: petroleum, chemical, petrochemical, building-and-construction, etc.


Design description and function

Structurally, RIZUR-SGL-N consists of:

  • housing (material: elastomeric thermoplastic, PTFE);
  • tinned copper braid, that provides shielding, grounding and cable protection against mechanical impacts;
  • insulation made from elastomeric thermoplastic, that protects the matrix from moisture and galling;
  • self-regulating semi-conductive matrix;
  • copper tinned conductor providing constant voltage supply along the full length of the cable.

Advantages of RIZUR-SGL-N

  • Safe and reliable. It does not overburn or overheat even in case of self-crossing due to self-regulation of heat release.
  • The cable can be cut to the necessary length without any loss in its qualities (to correspond to the pipeline length).
  • Easy and quick mounting. All the necessary mounting elements for cable connection and control are in the scope of supply.
  • The cable can be used in various conditions: hazardous and non-hazardous, corrosive, explosion-hazardous.
  • It has a wide working voltage range: 220-240 V and 110-120 V (customized design variants).
