BTTZ cable

BTTZ is a cable that uses minerals (magnesium oxide) as insulation material. Usually composed of copper conductors, mineral insulation, and copper sheaths, without organic materials. It has the characteristics of being non flammable, smokeless, non-toxic, and fire-resistant.

Product Overview

Copper core copper sheathed magnesium oxide insulated heavy-duty fire-resistant cable (also known as heavy-duty mineral insulated cable) is a new type of cable that uses seamless copper tube sheathing on the outer layer and magnesium oxide crystal powder as insulation material in the middle. The conductor is composed of single stranded copper rods.

Main features

It has the characteristics of high temperature resistance, fire resistance, explosion prevention, non combustion (can operate continuously for a long time at 250 ℃, and can also operate for a short time for 30 minutes at the limit state of 1000 ℃), large current carrying capacity, small outer diameter, high mechanical strength, long service life, and generally does not require independent grounding wires.

Application scope

Good fire resistance is one of the superior characteristics of mineral insulated cables. Therefore, when choosing mineral insulated cables, people associate it with fire resistance requirements, and it is also commonly referred to as "fire-resistant cables". In fact, its applicability is very wide, and it can be applied at sea, land, indoor and outdoor, above ground and underground; Especially in historic buildings, super high-rise buildings, hotels, shopping malls, hospitals, airports, television stations, communication hub projects, ships, theaters, ancient buildings, subways, civil defense projects, public places with dense pedestrian flow, and dangerous places prone to fire (such as natural gas plants, chemical plants, refineries, and offshore oil platforms), they are widely used. It can also be applied to places with high environmental temperatures, such as power plants and steel plants. It has also been applied in special environments such as anti electromagnetic interference, anti animal biting, waterproofing, nuclear power plants, and food processing plants with high hygiene requirements.

Mineral insulated cables can be used in the above-mentioned locations for backbone and branch distribution systems, general lighting, internal wiring of machinery and equipment, intrinsic safety circuits, emergency lighting, emergency backup power supply, information data transmission and control circuits of firefighting related equipment, potential explosion hazard areas, etc.
