Executive Summary 执行摘要
The Australian and New Zealand mining cable standards AS/NZS 1802:2003 and AS/NZS 2802:2000 represent the definitive technical specifications for elastomer-insulated, elastomer-sheathed reeling and trailing electric cables used in mining operations. These standards govern the construction, testing, and performance requirements for cables that form the electrical lifeline of mining machinery across the Asia-Pacific region. 澳大利亚和新西兰矿用电缆标准 AS/NZS 1802:2003 与 AS/NZS 2802:2000 是弹性体绝缘、弹性体护套卷筒和牵引电缆的权威技术规范，广泛应用于亚太地区的采矿作业。
AS/NZS 1802:2003 specifically addresses cables for underground coal mining operations, where methane gas hazards and confined space requirements demand exceptional safety standards. The standard mandates electrical symmetry for alternating current supply cables—a critical safety feature that ensures balanced electromagnetic fields within the mining environment. AS/NZS 1802:2003 专门针对井下煤矿作业电缆，鉴于甲烷气体危害和受限空间的要求，该标准对交流供电电缆强制规定了电气对称性——这是确保采矿环境内电磁场平衡的关键安全特性。
AS/NZS 2802:2000 covers cables for surface mining, underground mining (excluding coal), and general industrial applications, with voltage ratings from 1.1/1.1 kV up to 33/33 kV. This standard incorporates Amendment No. 1 (December 2003) and provides specifications for two distinct cable classes based on insulation and sheath thickness. AS/NZS 2802:2000 涵盖露天矿、非煤井下矿及通用工业应用电缆，电压等级从 1.1/1.1 kV 至 33/33 kV。该标准包含2003年12月的第1号修订版，并根据绝缘和护套厚度提供两种不同电缆等级的规格。
