product description: Copper core copper sheathed magnesium oxide insulated heavy-duty fireproof cable (also known as heavy-duty mineral insulated cable), is a kind of outer layer with seamless copper tube sheath, and the middle is filled with magnesium oxide
crystal powder as insulation material. The conductor is single-stranded A new type of cable composed of copper rods.
Mainfeatures:
It is resistant to high temperature, fireproof, explosion-proof, non-combustible (continuous long-term operation at
250°C, and short-term operation of 30min at 1000°C limit). It has large current carrying capacity, small outer diameter, high
mechanical strength, and generally does not The characteristics of a separate grounding wire are required.
Applications:
Better fire resistance is one of the characteristics of mineral insulated cables. Therefore, when people choose mineral insulated cables, they associate it with the fire resistance requirements, and they are also used to call them "fireproof cables". In fact, it has a wide range of applications, which can be applied on sea, land, indoor and outdoor, ground and underground; especially in historic buildings, super high-rise buildings, hotels, shopping malls, hospitals, airports, television stations, communication hub projects, and ships , Theaters, ancient buildings, subways, civil air defense projects, crowded public places, and dangerous places prone to fire (such as natural gas plants, chemical plants, oil refineries, offshore oil platforms) are widely used. It can also be applied to places with high ambient temperature, such as power plants and steel plants. For special environments, such as anti-electromagnetic interference, anti-biting, waterproof, nuclear power plants, and food processing plants that require high sanitary conditions are also used.
Mineral insulated cables can be used in the above-mentioned places for mains, branch distribution systems, general lighting, internal wiring of machinery and equipment, intrinsically safe circuits, emergency lighting, emergency backup power supplies, information data transmission and control lines for fire-related equipment, and potential explosion hazards Area.
