Product Description

Product Description

  Shenghua Jiaolian Mineral Insulated Fire-Resistant Copper Conductor Power wire and cable

BTTW is a flame-retardant, copper-core mineral insulated power cable designed for critical fire-resistant circuits. Rated at 750V voltage grade.

 It features a seamless copper sheath and compacted magnesium oxide insulation, ensuring exceptional fire integrity (withstands 950°C/3h) and mechanical durability. Ideal for emergency lighting, fire alarms, and HVAC systems in high-rises, subways, and industrial plants.

Its structure eliminates organic materials, preventing smoke or toxic emissions. Key performance advantages include superior short-circuit resistance, moisture-proof properties, and a 120-year service life. Certified to GB/T 13033 and IEC standards, it meets stringent fire safety certifications globally. 

The functional design guarantees circuit integrity during fires, enabling reliable power transmission in extreme conditions.

Cable Constructions

Layer/Component	Material & Specification	Primary Function
1. Conductor	Annealed bare copper (solid or stranded)	Carries electrical current. Stranded conductors offer greater flexibility.
2. Conductor Insulation	Magnesium Oxide (MgO) powder, highly compacted	Provides superior fire resistance, high-temperature stability (typically up to 250°C), and excellent dielectric properties. Acts as the primary insulation.2
3. Sheath (Inner)	Seamless copper tube	Encases the MgO-insulated conductors. Provides mechanical protection, moisture barrier, and acts as a ground path.5
4. Insulation (Overall)	Mineral (MgO) core within copper sheath	Maintains fire resistance and electrical integrity under extreme conditions.
5. Outer Sheath/Jacket	Thermoplastic, Moisture & Flame-Retardant (e.g., PVC, LSFZH)	Provides final mechanical protection, UV resistance (if required), and enhanced moisture resistance ("W" rating). Colored for identification. Meets international flame/smoke/toxicity standards (e.g., IEC/BS/UL).
