Abstract
The invention provides a flexible mineral insulated cable comprising wire cores, a composite filling layer which wraps the wire cores, a fire-resistant layer which wraps outside the composite filling layer and an external sheath which extrudes outside the fire-resistant layer. Each wire core comprises conductors, an insulating layer which extrudes outside the conductors and a wrapping layer which wraps outside the insulating layer. The wrapping layer is formed by a polyimide adhesive tape, a shielding coating layer which is coated outside the polyimide adhesive tape and a single-side phlogopite tape which wraps outside the shielding coating layer. The composite filling layer is formed by cable PP filling ropes and mica powder. The fire-resistant layer is the single-side phlogopite tape. The external sheath is an ethane-vinyl acetate copolymer. The flexible mineral insulated cable has excellent electrical insulation performance, high temperature resistance and low temperature resistance and excellent fire-resistant, environment-friendly and anti-interference performance and high cost performance. Especially the cable adopts a special coating shielding mode so that the cable has excellent electromagnetic interference resistance, lightning stroke protection, potential equalization and power supply quality improvement properties and has great bending performance.
