Product Overview
The Type 409 series mining cable is primarily engineered as a flexible feeder cable for power supply to machinery and equipment in mining operations. It is specifically designed for trailing applications rather than continuous reeling. The series encompasses a wide range of sizes, with smaller cables utilized for drills, hand-held tools, and portable equipment, while larger configurations provide reliable power to heavy machinery including draglines, shovels, and large drills.
Standards
-
AS/NZS 2802:2000 – Electric cables – Reeling and trailing for mining and general use
