What are helical resistors?
Helical resistors are electrical components manufactured with a conductive wire wound in a spiral shape around an insulating or ceramic core, which allows them to withstand high energy loads and dissipate heat efficiently. Their helical structure facilitates a uniform distribution of electrical current, reducing the risk of hot spots and improving their performance under demanding conditions.
They are essential in applications such as industrial braking systems, load banks, automated machinery and power controls in production processes.
What is a helical resistor?
The spiral design allows uniform heat distribution, optimizing performance in large-scale electrical systems and advanced power structures.
Manufactured with high thermal conductivity materials and protected with corrosion-resistant coatings, these resistors ensure stable operation even under extreme conditions. Their helical structure not only improves heat dissipation, but also reduces the possibility of overloads, extending equipment life and reducing the need for frequent maintenance.
Enables high power dissipation in a small space. This set, with side supports and galvanized steel box perforated to ensure proper ventilation, complies with the IP20 or IP23 protection requirement. They can be supplied with thermal protector and with the ohmic value required by the customer.
Low temperature coefficient offering a constant ohmic value (temperature dependent parameter) over a wide temperature range. The power resistors, being passive elements, are not affected by specific EMC standards.
How does it complement other devices?
In the industrial field, helical heaters are essential in heating systems, electric furnaces, processing machinery and power distribution networks. Their ability to operate at high electrical loads makes them an essential component in the thermal regulation of critical infrastructures, ensuring efficiency and operational safety.
In addition to their mechanical and thermal resistance, these units offer flexibility in their design, allowing specific adaptations according to the requirements of each installation. This makes them ideal for applications where precision and consistent performance are essential.
