Discover HELUKABEL's HELUTHERM 145 MULTI-C fire-resistant signal cable. Effectively fireproof, high-quality, and durable in all industrial environments.
1. What are fire-resistant signal cables?
Fire-resistant signal cables are designed for transmitting signals, audio, and video across various fields and industries, particularly in harsh environments prone to fire hazards or high levels of interference. These cables are suitable for use in elevator systems, security cameras, audio systems, and machinery.
In addition to transmitting signals, audio, and video, signal cables can send information to control centers regarding the status and operational locations of monitored machines and equipment. These cables support remote control functions and serve as an effective solution in the field of industrial automation.
2. Benefits of using fire-resistant signal cables
Choosing fire-resistant signal cables, such as the HELUTHERM 145 MULTI-C series, brings significant benefits to industrial systems and commercial buildings:
- High safety in hazadous environments: Fire-resistant signal cables are designed to withstand heat and prevent the spread of flames, minimizing the risk of fire propagation. This is especially important in industrial areas, factories, or buildings with high fire and explosion risk, ensuring the safety of people and assets.
- Continuous signal maintenance during emergencies: In the event of a fire, standard cables can easily lose signal or become damaged. Fire-resistant cables are engineered to maintain signal integrity for an extended period, even under high heat, allowing fire alarm, security, and communication systems to operate reliably for timely responses.
- Enhanced durability and strength: Made from premium, heat-resistant, fireproof materials, fire-resistant signal cables have a longer lifespan and require less maintenance, helping businesses save costs over the long term.
- Compliance with international standards: HELUKABEL's fire-resistant signal cables meet international safety standards, such as IEC and UL, making it easier for businesses to comply with fire protection regulations, particularly in industries with stringent safety requirements.
- Reduced environmental impacts: HELUKABEL’s fire-resistant cables are often manufactured from halogen-free materials, reducing the emission of toxic smoke when burned, making them more environmentally friendly and safer for human health.
3. Applications of fire-resistant signal cables
Fire-resistant signal cables are widely used in various industries and construction projects due to their high heat resistance and ability to ensure safety in case of fire. Typical applications include:
- Fire alarm and security systems: Fire-resistant signal cables are essential components in fire alarm and security monitoring systems, maintaining communication during a fire to ensure timely transmission of alerts.
- Energy industries: In power plants, especially thermal power plants and renewable energy facilities, fire-resistant cables protect electrical equipment and data under high-temperature conditions, ensuring the safety of operational systems.
- Transportation system and ỉnastructure: Fire-resistant cables are commonly used in transportation signal systems, train stations, airports, and other public infrastructure to maintain continuous operation even during a fire, helping to ensure the safety of passengers and staff.
- Commercial and residential buildings: In high-rise buildings, fire-resistant cables protect electrical and communication systems, preventing signal loss and enabling firefighters to access critical information in emergency situations.
- Heavy industrial manufacturing: In industries such as steel, cement, and chemicals, fire-resistant cables are ideal due to their high heat tolerance, ensuring stability and protecting transmitted signals even in high-temperature and harsh environments.
- Oil and gas industry: Used in areas prone to fire and explosions, fire-resistant signal cables help minimize the spread of flames, protecting the safety of personnel and equipment in these hazardous settings.
