What is AS/NZS 2802 Type 441 Trailing Mining Cable?
Blog Article
The AS/NZS 2802 Type 441 Trailing Mining Cable is a specialized cable designed for robust mining applications. It complies with Australian and New Zealand standards (AS/NZS 2802:2000), ensuring its suitability for the harsh conditions typical in mining environments.
Key Features and Specifications:
- Conductor: The cable features flexible stranded tinned annealed copper conductors, which provide excellent conductivity and flexibility.
- Insulation: It is insulated with Ethylene Propylene Rubber (EPR), which offers superior thermal and electrical properties.
- Screening: The cable includes a semi-conductive tape for insulation screening and a semi-conductive PCP cradle separator that supports and protects the power cores.
- Sheath: The outer sheath is made of heavy-duty PCP, known for its durability and resistance to mechanical stress, abrasion, and environmental factors.
- Earth Conductors: It has interstitial earth conductors made of semi-conductive PCP insulated flexible stranded tinned copper.
- Central Pilot: A central extensible pilot made of EPR-covered flexible stranded tinned copper conductor is included to enhance safety and operational efficiency.
Applications:
Type 441 cables are primarily used in mining operations for trailing and reeling applications. They are designed to handle the mechanical stresses associated with such environments, such as crushing, squashing, and bending. This makes them ideal for powering heavy mining machinery and equipment.
Variants:
Type 441 cables come in various sizes and voltage ratings to accommodate different operational needs. They are available in sizes ranging from 6mm² to 240mm², with voltage ratings up to 6.6kV. Report this page
