Product Description:

The GWK Self-Regulating Heating Cable is designed for freeze protection and process temperature maintenance of metal and non-meta pipes and vessels and equipment.

The unique PTC feature of GWK self-regulating core elements adjust its heat output in response to the surrounding temperature along the entire circuit, delivering more heat where and when required.This self-regulating feature also serves to prevent overheating, even in cases where GWK cables overlap. Another benefit of the cable is the ability to cut to length in the field, completed with Huaning system connection kits for quick and convenient installations.

GWK heating cable system is certified for ordinary and hazardous areas with maximum maintain temperature of 120°C (250°F) and intermittent exposure temperature of 200°C (392°F). Use of Huaning connection kits for GWK installation is required to comply with system approval, ensuring safe operation and reliable thermal performance.

Specification:

HUANING offers system components for power connections, splice or tee connections and end terminations to ensure proper functioning of the products and comply with warranty and approvals requirements.

For easier installation and safe operation, use of substituted parts are not recommended. Please contact HUANING for more information on system components.

Product Advantages:

(1) Automatically adjust the output power and compensate according to the actual heat required by the heat tracing system, which is a new generation of energy-saving constant temperature heater.

(2) It can be arbitrarily shortened or extended within a certain range, and it can be overlapped multiple times without the concern of high temperature hot spots and burnout, uniform temperature, because each part can be.

(3) Low temperature, fas+ Startrature change of the heat-tracing place. automatically adjusted due to the temper.

(4) Easy installation, simple maintenance, all-day service, high level of automation, and low operating and maintenance costs.

(5) It is safe and reliable, widely used, no pollution to the environment, long service life.

GWK Power-Temperature Characteristics

Nominal Power Output Ratings on Insulated Metal Pipes at 230 V

[Note]

1. Thermal outputs above are tested in accordance with IEEE 515, with each model on a metallic pipe insulated with a fiberglass insulation.

2. For plastic pipe installations, the power output will be derated by 35% and use aluminum tape install method.

Max. Circuit Length based on Circuit Breaker Selection

[Note]

1. The circuit lengths are based on trip current characteristics of Type 00 and Type 0CB devices. For devices with different trip characteristics please consult with Shandong Huaning.

2. Use local electrical codes to select appropriate branch circuit breakers.

3. The total length of heating cables connected to the circuit breaker is the sum of all cables that have been so iced or interconnected in parallel. Ensure that the total length do not exceed the maximum circuit length as indicated above.

4. Ground fault protection of equipment is required for heat tracing branch circuits with typical trip level of 30mA. Thermal magnetic breakers are recommended to reduce nuisance tripping.

5. It is recommended to start up the circuits at higher temperatures, when possible, to avoid large start-up or in-rush current which may trip the circuit breaker.
