Coast 1.0mm Twin W/E
The Coast 1.0mm Twin Cable provides a high-reliability solution for domestic lighting and low-power electrical circuits. It utilizes two insulated solid copper conductors alongside a central earth wire. This flat-profile cable facilitates easy routing within building structures and narrow conduits. High-purity annealed copper ensures the conductors maintain optimal conductivity and low thermal resistance. The specific 1.0mm² cross-sectional area supports standard current loads for residential illumination systems. Each core features color-coded PVC insulation to prevent electrical faults and simplify installation. A robust outer sheath protects the internal components from mechanical stress and environmental factors.

The insulation on this Coast cable is tough and doesn’t peel off easily like some of these cheap brands in the market. Used it for the lighting circuit in my extension in Kitengela and the electrician was happy with the quality. Good value for money if you want something that will last without issues.
