What are the product features of copper-sheathed magnesium oxide insulated fire-resistant cables (BTTZ/BTTVZ/BTTYZ/BTTQ/BTTVQ/BTTYQ)?
1. Cable lengths generally meet customer needs; a 300-square-meter cable can be produced in 400-meter lengths.
2. Long production lengths reduce or eliminate intermediate connectors, improving line reliability and installation efficiency. This can save labor and intermediate connector costs by approximately 10%-15% of the total cable price.
3. Precise positioning using a mechanical device ensures concentricity between the sheath and conductor.
