High-temperature resistant and flame retardant cables are cables designed for safe use in high-temperature environments or potentially fire-hazardous areas, and they possess two important characteristics: high-temperature resistance and flame retardancy. Insulation resistance is a measure of the ability of a cable’s insulating material to block the passage of electric current, and is measured in megohms (MΩ). When you hear someone mention “high-temperature resistant and flame retardant cable insulation resistance ≥ 10,000 MΩ”, this indicates that the insulation resistance value of this cable measured under certain conditions is at least 10,000 megohms, which is a very high standard, reflecting the superiority of this cable in insulation performance.
Importance of insulation resistance
Enhanced safety: High insulation resistance prevents leakage of electricity when the cable is not energized, reducing the risk of electric shock, especially important in humid or flammable environments.
Signal transmission quality: For cables transmitting signals, high insulation resistance means that signals are subject to less interference during transmission, ensuring signal purity and transmission efficiency.
Long-term stability: high insulation resistance also means that the insulation material of the cable is not easy to age, and can maintain good electrical performance for a long time, extending its service life.
Features of high temperature resistant flame retardant cable
High Temperature Resistance: It can maintain normal operation under high temperature environment (e.g. 150℃ to 1000℃, depending on the design), and the insulation performance will not decrease rapidly due to high temperature.
Flame retardant: In case of fire, the outer sheath and insulation layer of the cable can effectively inhibit the spread of fire, reduce the risk of fire, and buy valuable time for the evacuation of personnel and fire extinguishing.
Special materials: High temperature resistant, low smoke, halogen free or other specially formulated insulation and sheath materials are used to meet high standards of fire safety.
Mechanical strength: usually with good mechanical properties, can withstand a certain degree of external impact and mechanical stretching, suitable for complex installation environment.
Cable insulation resistance reaches 10000MΩ reason and significance
Reaching such a high insulation resistance value indicates that the cable is made of high-quality insulating materials and undergoes a strict manufacturing and quality control process. This is not just a number, but also a commitment to the stability of the cable under extreme conditions, to ensure the safe operation of the cable at high temperatures, high loads, and in harsh environments, and to provide a solid guarantee for power transmission and signal control, especially in the fields of petroleum, chemical industry, metallurgy, nuclear power, aerospace, military, and medical care, where this performance is particularly critical.
Technical measures to realize 10000MΩ high insulation resistance
- Selected insulation materials: high temperature flame retardant cables usually use high-performance insulation materials such as fluorine plastic (e.g. FEP, PFA), silicone rubber, cross-linked polyethylene (XLPE cable). These materials not only have excellent high-temperature resistance, but also maintain good insulation at high temperatures, ensuring that even at extreme temperatures, the cable’s insulation resistance of 10,000MΩ still far exceeds the standard requirements.
- Optimized cable structure design: By accurately calculating and designing the cable’s conductor cross-section, insulation thickness and sheath structure, we can reduce defects within the insulation layer, such as air bubbles and impurities, which can be factors in lowering insulation resistance. Optimized design can effectively improve the overall insulation performance of the cable.
- Strict quality control: During the manufacturing process, we ensure that each batch of cables meets the expected insulation resistance standard of over 10,000MΩ by implementing strict raw material inspection, production process control and finished product testing. This includes the use of a clean workshop environment during the manufacturing process to prevent foreign contaminants from affecting the quality of the insulation layer.
- Special Manufacturing Processes: For example, the cross-linking process can significantly improve the heat resistance and mechanical properties of polyethylene materials, enabling them to maintain good insulation properties at high temperatures. In addition, the electrical insulation properties of the material can be further enhanced by special formulations and process treatments.
Insulation resistance 10000MΩ cable application value and significance
Enhance system reliability: In power transmission and automation control systems, cables with high insulation resistance can significantly reduce short-circuits, disconnections and other faults caused by insulation damage, thus improving the stability and reliability of the entire system.
Environmental protection: Cables with high temperature resistance, flame retardant and high insulation properties, especially those of low-smoke, halogen-free varieties, reduce fire hazards, while releasing very few hazardous substances in case of fire, which is conducive to the protection of the environment and the safety of personnel.
Economic benefits: Although the initial investment may be relatively high, it can save customers a lot of money in the long run and improve economic benefits due to its excellent durability and reduced maintenance costs.
