Refractory, low smoke halogen free polymer insulated and sheathed flame-retardant power cables are designed for power transmission and distribution at rated AC voltages of 1 kv and 0.66 or 100 Hz of the frequency fixing device.
Conductor: copper, solid. Weave: Two pieces of mica tape.
Polyethylene terephthalate film is allowed on mica tape.
Insulation: Halogen-free polymer composite.
Chain: Insulated conductor multi-core cable arestranded as the core.
Filler: The insulated conductors between the inner layer of the near-round power cable and outer space shall be filled with plastic (with halogen-free polymer composite kordel).
