Product code	MU1504004
Sales unit	Meter
ETIM-Class	EC000034

Product specifications

4F G657A1 Ultra-Lightweight (ULW) aerial cables are designed for overhead pole installation. But can also be Installed underground in ducts by pulling. Cable parameters such as cable diameter, stiffness and tensile strength are optimized for best installation performance. Openreach PIA approved, suitable for use alongside 11kV power cables and with tensile breaking force for maximum security, less than 2000N.
