Rubber Sheath Flexible Cable

Introduction

These cables are designed to provide high flexibility and have the capacity to withstand weather, oil/grease, mechanical and thermal stresses. Applications include handling equipment, mobile power supplies, worksites, stage and audio visual equipment. Also for use in drainage and water treatment, cold environments and severe industrial environments.
