Product Overview
The Type 455 series medium voltage mining cable is engineered for applications where minimal diameter and reduced mass are critical requirements. Designed with reduced insulation and sheath thickness and featuring a cradle-free construction, these cables are particularly suited for stacker-reclaimer operations and other mobile equipment where weight and space constraints are paramount. With two earth conductors and one pilot conductor (all same size) positioned in the outer interstices, this cable delivers reliable performance in both reeling and trailing applications while maintaining full compliance with Australian/New Zealand standards.

Construction
The Type 455 cable features an optimized construction designed to reduce diameter and mass while maintaining electrical integrity and mechanical strength.
| Component | Description |
|---|---|
| Conductors (3×) | Flexible stranded tinned annealed copper conductors. |
| Conductor Screen | Polyester barrier tape plus extruded semi-conductive tape. |
| Insulation | Ethylene Propylene Rubber (EPR) – reduced thickness design. |
| Insulation Screen | Semi-conductive tape applied over insulation. |
| Filler | Elastomer center filler to maintain circular form. |
| Interstitial Earth Conductors (2×) | CSP (Chlorosulfonated Polyethylene) insulated flexible stranded tinned copper conductors, positioned in outer interstices. |
| Interstitial Pilot (1×) | EPR-insulated flexible stranded tinned copper conductor, positioned in outer interstices (same size as earth conductors). |
| Textile Reinforcement | Open-weave braid reinforcement for mechanical strength. |
| Sheath | Extra-heavy duty Polychloroprene (PCP) sheath – reduced thickness design, providing excellent abrasion, oil, and weather resistance. |
