How to Maintain and Test Heat Resistant Cables for Long-Term Durability

How Fire Survival Cables Differ from Fire-resistant Cables
Oct 30, 2024

In India’s rapidly growing industrial landscape, the demand for reliable heat-resistant cables has never been higher. As leading heat-resistant cables manufacturers in India continue to innovate, understanding proper maintenance and testing procedures becomes crucial for maximising your investment. 

Whether you’re operating a steel plant or managing a power facility, the longevity of these specialised cables can make or break your operations. Let’s explore expert-backed strategies to ensure your heat-resistant cables perform optimally in India’s diverse industrial environments.

What are Heat-resistant Cables?

Heat-proof flexible copper braid cables are engineered with sophisticated materials and insulation systems that can endure elevated temperatures without compromising their electrical or mechanical properties. The construction typically incorporates high-performance materials such as:

  • Silicone rubber insulation
  • Cross-linked polyethylene 
  • Fluoropolymer compounds
  • Mineral insulation with metal sheaths

What are the Signs of Cable Deterioration?

Identifying the early warning signs of cables deterioration may prevent costly failures and system downtime. You should watch for these important indicators, including:

  • Discolouration or charging
  • Stiff insulation material
  • Unusual odours during operation
  • Elevated operating temperatures
  • Inconsistent electrical performance

How Do I Test the Heat-Resistant Cables?

There are several ways to test the long-term durability of this type of cable. The following are:

Thermal Stability Testing

Once the cables are placed in thermal heating equipment, this test measures the time that it takes for a universal indicating paper. The average value of the three samples should not be lower than the value specified in the standard for that type of cable. 

Temperature Chambers

These temperature chambers can cycle cables between high and low temperatures to stimulate outdoor weathering. This helps you to determine the thermal stability of the cable and resistance to temperature-related degradation. 

High voltage exposure and UV chamber

The centre sections of the wire are submerged in the water, a high voltage is placed on the conductor, and a ground return is placed in the water bath. Expose the cables jacketing to continuous ultraviolet radiation to simulate long-term exposure to sunlight.

Essential Maintenance Procedures

Remember that proper maintenance is actually the basis of cable life and integrity. A good maintenance program should have scheduled visual inspections, which are conducted monthly. During such inspections, technicians must scrutinize the heat-proof flexible copper braid cables for signs of any physical damage, wear patterns, or deterioration. Strong emphasis is placed on areas where cables are subjected to maximum temperatures or mechanical stress.

Much attention must be paid to details while cleaning. It is achieved by only using approved methods and materials in cleaning in order to prevent accidental damage. Regular cleaning will prevent the accumulation of degrading substances that may damage the protective outer layer of the cable. Around the installations, adequate ventilation must be provided to avoid heat buildup and maintain its optimum operating condition.

What Should You Follow to Maintain Long-Term Durability?

Implementing best practices ensures maximum service life for heat-resistant cables. During installation, strictly adhere to manufacturer guidelines regarding bend radius and support systems. Regular inspections should be scheduled and performed by qualified personnel who understand the specific requirements of heat-resistant cable systems.

Preventive Maintenance Schedule

You can set a schedule in order to bring a planned maintenance routine with the introduction of generalized inspections and detailed inspections. Quarterly checks will comprise basic visual check-ups along with checking electrical parts. Annual inspection will involve a testing and analysis level of details. It, therefore identifies potential problems before they develop into major ones.
