The cable includes three large pilots and a central semiconductive cradle, which provides support and protection to the power cores, ensuring reliable performance and longevity.

Standards

The Type 441.22 cable conforms to the following standards:

- **AS/NZS 2802:2000**: Specifies the requirements for reeling and trailing cables for mining applications.

- **AS/NZS 1125**: Details the specifications for conductors in insulated electric cables and flexible cords.

- **AS/NZS 3808**: Specifies the requirements for insulation and sheath materials for electric cables.

- **AS/NZS 5000.1**: Outlines the general requirements for electric cables.

Construction

- **Conductors:** The cable features three flexible stranded tinned annealed copper conductors, which provide excellent conductivity and flexibility.

- **Conductor Screen:** Polyester barrier tape screens the conductors, ensuring electrical insulation and mechanical protection.

- **Insulation:** Insulated with Ethylene Propylene Rubber (EPR), the conductors benefit from superior thermal stability and electrical insulation.

- **Insulation Screen:** Semiconductive tape further screens the insulation, enhancing electrical safety and performance.

- **Central Semiconductive Cradle:** A critical component, the central semiconductive Polychloroprene (PCP) cradle, offers support and protection to the power cores.

This cradle stabilizes the cores, preventing mechanical stress and ensuring consistent performance under harsh conditions.

- **Overall Core Screen:** The overall core is filled and covered with semiconductive PCP, providing additional mechanical and electrical protection.

- **Interstitial Earth Conductors:** Three interstitial earth conductors, semiconductive PCP insulated flexible stranded tinned copper conductors, are included.

- **Central Extensible Pilot:** A single central extensible pilot conductor is covered with EPR and made of flexible stranded tinned copper.

- **Textile Reinforcement:** The cable incorporates open-weave braid reinforcement, adding mechanical strength and durability.

- **Sheath:** The outer sheath is made of heavy-duty PCP, which is resistant to mechanical wear and environmental factors, ensuring robust protection.

Advantages

- **Mechanical Protection:** The cable's central semiconductive cradle and heavy-duty PCP sheath provide excellent mechanical protection, reducing the risk of damage and ensuring durability in mining environments.

- **Flexibility:** The flexible stranded conductors and robust design make the cable ideal for applications involving frequent movement and bending.

- **Electrical Performance:** EPR insulation and semiconductive screens ensure superior electrical properties, reducing the risk of electrical faults and enhancing operational reliability.

- **Stability and Support:** The central semiconductive cradle offers crucial support to the power cores, maintaining cable integrity under high mechanical stresses and enhancing overall performance.

Usage

These cables are particularly useful in mining operations where machinery and equipment require a reliable power supply through flexible and durable trailing cables.

The design accommodates high mechanical stresses typically encountered in mining environments, making it an ideal choice for power supply to excavators, draglines, shovels, and other heavy machinery.

In conclusion, Type 441.22 Reeling & Trailing Mining Cable, compliant with AS/NZS 2802:2000 standards, provides a reliable and durable solution for power supply in mining applications. Its central semiconductive cradle is a pivotal feature that ensures mechanical stability and support for the power cores, making it ideal for the demanding conditions of mining operations.
