RTTZ Series Corrugated Copper Metalllc Sheath Mica Tape Mlneral Insulated Cable with a Rated Voltage up to and Including 0.6/1 kV

Executive Standards

This product is produced in accordance wth the standard ofGBr 34926 «Corrugated Copper Metallic Sheath Mica Tape Mineral Insulated Cables and Their Terminations with a Rated Voltage Up To and Including 0.6/1 kV»

Scope of Application

Mainly suitable for high-rise buildings, entertainment venues, and numerous construction projects that require high quality and high safety productsin large cities.
Applicable to applications where GB 51348 «Standard for Electrical Design of Civil Buildings» stipulates that "mineralInsulated cables should have flame retardant performance not lower than B, level', such as fire pumps. fire control rooms.fire elevators, fire lighting, etc.

Product Structure

1. Conductor: Made of multiple stranded copper wires, it has good bending and electrical properties.
2. Insulation layer: Inorganic insulation materials wth high temperature resitstance and high insulation resistance are used.
3.Protective layer: using fiame-retardant fape that is resistant to high temperatures and compatible with insulation maferials
4. Metal sheath: Made of copper material, It has good bending characteristics after forming, welding, and rolling
5. Outer protective layer: If necessary, a plastic protective layer can be extruded outside the metal copper sheath to provide good corrosion resistance.
