This product is a specialized cable designed for internal wiring in switchgear and distribution panels, suitable for electrical systems with an AC rated voltage not exceeding 1000 volts or a DC voltage not exceeding 750 volts.
The cable adopts a halogen-free low-smoke (LSOH) design, which does not release corrosive gases during combustion, effectively protecting electronic equipment safety. It is particularly suitable for public spaces and government buildings with strict restrictions on smoke and toxic gases. With a maximum operating temperature of 90°C, it is ideal for conduit installation or internal equipment wiring.
The product complies with multiple international standards, including CEI, CENELEC, EN, and the EU Low Voltage Directive, and has passed RoHS environmental certification. The cable core uses copper conductors conforming to IEC 60228 standards, and the insulation layer is made of cross-linked polyolefin material, offering excellent flame retardancy, flexibility, and insulation performance to ensure stable and reliable connections under complex working conditions.
Key models include H05Z-U, H07Z-U, and H07Z-R, covering a wide range of cross-sectional specifications from 0.5mm² to 240mm². This variety meets different current loads and installation space requirements, making it an ideal wiring solution for building electrical systems, equipment power distribution, and locations with high safety demands.
