Self-regulating heating cable for temperature maintenance applications 150 mètres 31 w/m

Benefits:

Energy savings:

• The cable consumes only the energy it needs based on outdoor temperature conditions at any given moment. Its consumption therefore varies strictly in proportion to the installation’s needs.

• The power dissipated per meter is independent of the total length of the cable installed. This allows the cable to be cut to the exact desired length without changing the power per meter, making it very easy to use.

Safety:

The “self-regulating” technology prevents the cord from overheating and allows it to be placed side-by-side when protecting faucets or other plumbing fixtures. Its metal braid also provides personal protection by grounding the heating cord.

Durability:

Laboratory tests and experience gained from thousands of kilometers of installed cable demonstrate the product’s longevity.

Simplicity:

Few components and/or accessories.

Applications:

Maintaining domestic hot water temperature:

Today, it is essential to ensure the instantaneous supply of domestic hot water to every tap in the system at the lowest possible cost. The AUTOCÂBLE cord, by eliminating the traditional “domestic hot water loop,” keeps domestic hot water circulating continuously through the pipes.

• The investment is reduced (no more pump, heater, or return pipe)
• The system is highly efficient and reliable
• Consumption is optimized
• Maintenance is virtually nonexistent
• Installation requirements are reduced compared to installing a dual-loop system

Technical information:

Product structure:

The two copper conductors (1.25 mm² cross-section) are embedded in a “self-regulating” matrix that forms the core of the cable. The quality of the “component” and the cross-linking process determine the quality of the self-regulation and the durability of this property over time. Above the HDPE protective layer is a tinned copper metal braid used for grounding. Finally, the entire assembly is covered with a protective jacket made of polyolefin (BMX) or fluoropolymer (BMF).

Important:

Circuit breaker sizing for cold start:
1 - Select the system’s start-up temperature by setting the TH 40 thermostat between 0 °C and 40 °C.
2 - Based on the selected AUTOCÂBLE self-regulating cable and the set start-up temperature, determine the cold start current (see technical specifications table).
- Perform the calculation as follows: e.g.: Start-up at 10 °C of a 20 BMX cable, 90 m long

Total current = (Start-up current × 90 m) × 1.3
= 0.21 × 90 × 1.3
= 24.57 A

Rated amperage of standard circuit breakers:
10 - 16 - 20 - 21 - 32 - 40 - 50 - 63.
In this specific case, a single 32 A Type C circuit breaker should be used.
