Super Fire-Resistant Mineral Insulated Cable
Hengxun mineral insulated cable is a high-safety cable that uses inorganic minerals as the insulation layer. It can be used in your fire protection system, high-temperature projects and other scenarios. It can withstand temperatures up to 1000 degrees and can maintain long-term operation under extremely high temperatures. All our mineral insulated cables will undergo strict flame tests before leaving the factory, so please feel free to choose.
Ultra-Long-Life Mineral Insulated Cable
Hengxun mineral insulated cable has a service life of more than 50 years, far exceeding that of organic insulated cables. It is non-toxic and smokeless, and is particularly suitable for projects such as oil platforms and nuclear power plants. The use of copper sheath can make it have strong compression and tensile resistance, and can be directly buried without casing, greatly reducing your construction time and cost.
Mineral insulated cable is relatively expensive, so it is recommended to use it only in key areas, and flame-retardant cable should be used in ordinary areas.
Since the magnesium oxide powder in the insulation layer of conventional mineral insulated cable is hygroscopic, using it in a humid environment will cause the insulation resistance to decrease. If you need to use it in a humid environment, you must pay attention to the following:
- Strictly seal the terminal and the joint
- Prefer seamless copper sheath or waterproof sheath
- Avoid long-term immersion in water or acid-base corrosion environment
Mineral insulated cable used on offshore platforms is recommended to use stainless steel as the sheath, which can effectively resist salt spray and moisture.
