1. Comparison of working principles

Self-regulating heating cable:

Principle: Using positive temperature coefficient (PTC) material, the resistance increases with the temperature, and the power automatically decreases when the set temperature is reached, thus achieving self-regulation.

Features: Good temperature uniformity, no local overheating, no need for thermostat (can be used in combination to save energy).

Scenario: Applications that do not require high temperature accuracy, such as pipeline antifreeze, roof snow melting, and floor insulation.

 

Constant power heating cable:

Principle: Constant resistance, fixed power per unit length, and an external thermostat is required to adjust the temperature.

Features: Stable output, but precise temperature control is required, otherwise local overheating is prone to occur.

Applicable scenarios: Industrial equipment that requires constant heating, floor heating in large buildings (such as shopping malls, warehouses), etc.

 

2. Main selection factors

Factors Self-limiting temperature cable Constant power cable

Initial investment cost: high (composite material technology); weak (simple structure)

Operational energy efficiency: more energy-saving (automatic power regulation); thermostat required, otherwise energy may be wasted

Installation complexity: simple (can overlap, no strict spacing requirements); complex (fixed spacing is required to avoid overheating)

Maintenance requirements: low (self-protection function); high (depends on the reliability of the thermostat)

Temperature uniformity: better (automatic balance); depends on the accuracy of the thermostat

Lifespan: shorter (PTC material ages faster); longer (metal resistance wire is more durable)

 

3. Selection recommendations

Choose a self-limiting temperature cable in the following situations:

Non-continuous use scenarios, such as antifreeze, snow melting, etc.;

Complex installation space (such as curved pipes, roofs);

Sufficient budget, energy saving is a priority;

Sensitivity to overheating hazards (such as flammable environments).

Situations for choosing constant power cables:

Require long-term stable heating (such as industrial processes);

Uniform heating over a large area (with professional temperature control systems);

Limited initial budget and strong maintenance capabilities;

High temperature resistance requirements (self-limiting temperature cables generally have poor low temperature resistance).

 

4. Notes

Safety: Constant power cables must be used with a thermostat to prevent overheating; self-limiting temperature cables are safer but must still meet electrical specifications.

Energy efficiency certification: In long-term use scenarios, the energy-saving benefits of self-limiting temperature cables can offset their higher initial investment.

Professional design: For complex systems, it is recommended to consult an engineer to ensure that the cable power matches the heat load.

 

Evaluate the above factors according to actual needs, generally giving priority to safety, long-term costs, and applicability.

When choosing flooring for outdoor spaces, durability and appearance are key considerations. Terrazzo, with its long-standing history, offers both qualities, making it an excellent option for patios, pool areas, and garden paths. Its mixture of marble, granite, or glass chips embedded in cement or epoxy forms a robust, weather-resistant surface that can withstand UV rays, temperature changes, and heavy foot traffic. Unlike porous materials. Well-sealed terrazzo prevents water absorption, which helps avoid cracks and mold—an important benefit for outdoor settings.

To achieve a perfect terrazzo finish outdoors, specialized equipment is necessary. Contractors typically begin with a diamond grinding head for Husqvarna machine to level the surface and remove any flaws. This step is crucial for outdoor applications, as uneven surfaces can cause drainage problems or create tripping hazards. The accuracy of diamond grinding tool provides a solid base before the polishing process starts.

For precise edges and intricate details, polar magnetic diamond grinding tools offer exceptional control, particularly on curved areas like steps or decorative borders. Their secure magnetic attachment reduces slippage, ensuring uniform results. After grinding, wet polishing pads enhance the terrazzo’s characteristic shine while adding a slight texture for slip resistance—an important safety feature near pools or in wet condition.

In addition to its performance, terrazzo’s design versatility enhances outdoor aesthetics. Customizable aggregates allow for colors that harmonize with the natural environment, and its reflective properties improve ambient lighting. With low maintenance requirements and a timeless look, terrazzo is a wise investment for outdoor areas, blending artistry with lasting practicality.

Gutter heat cables typically reach temperatures between 100°F and 150°F (38°C to 65°C), but the exact maximum temperature depends on the type of cable:

What is the difference between a forged steel ball valve and a cast steel ball valve? The difference mainly lies in the processing technology and processing method of steel:

A cast steel ball valves is a kind of ball valve that is formed by pouring liquids into a mold and then allowing them to solidify. Alloy steel is the most common casting material. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel. Cast steel refers to a steel casting produced by a casting method. Cast steel is mainly used to make parts that are complex in shape, difficult to forge or cut, and require high strength and plasticity.

Forged steel ball valves are various ball valves with forged steel and forged pieces produced by forging process. Forged steel ball valves are stronger than cast steel ball valves and canbear large impact forces. Their plasticity, toughness and other mechanical properties are also higher than that of castings, so for some important machine parts, forged steel parts should be used.

Casting is liquid molding, while forging is a plastic deformation process. With improved internal structure, good mechanical properties and even grain texture, the forged work-piece is the perfect choice for important heavy-duty parts. The castingmay cause structural segregation, structural defects, but of course, casting has its own pros. The forming of complex work-pieces is not easy to be done by forging, in this case, casting process is more favorable.

Dervos is a leading industrial valve maker and trader in China, specializing in the production of ball valves.In addition to those incommon conditions, we also produce other special valves, OEM products and so on.To learn more about our industry-leading products, contact us today.
