The Australian and New Zealand electrical cable markets have been historically dominated by two major premium brands that established strong reputations over decades of operation. Olex Versolex, manufactured by Nexans Australia (formerly Olex Cables), represents a flagship line of flexible single-core and multicore power cables that comply fully with AS/NZS 5000.1 standards. These cables feature Class 5 flexible copper conductors, X-90 XLPE (Cross-Linked Polyethylene) insulation rated for 90 degrees Celsius continuous operation, and TPE-90 or PVC sheathing suitable for a wide range of commercial, industrial, and mining applications. The Versolex range has earned recognition for its robustness, durability, and suitability for submersible applications up to 500 meters depth, making it a preferred choice for demanding installations where reliability is paramount. 澳大利亚和新西兰电缆市场历来由两个在数十年运营中建立了强大声誉的主要高端品牌主导。由Nexans澳大利亚（前身为Olex电缆）制造的Olex Versolex代表了一系列旗舰柔性单芯和多芯电力电缆，完全符合AS/NZS 5000.1标准。这些电缆采用5类柔性铜导体、额定90摄氏度连续运行的X-90 XLPE（交联聚乙烯）绝缘以及适用于各种商业、工业和采矿应用的TPE-90或PVC护套。

Harmonised Cables, commonly known as HAR cables, conform to harmonisation documents set out by CENELEC (Comité Européen de Normalisation Électrotechnique), the European Committee for Electrotechnical Standardisation. HAR cables have a single system of designation code used across all European member states, meeting the norms set out in harmonisation documents HD 361 and DIN VDE 0292. This unified coding system eliminates confusion and facilitates trade between the 33 member and 14 affiliate countries of CENELEC.

British Standard BS8436 specifies requirements for multicore electric cables with low emissions of smoke and corrosive gases when subjected to fire. The standard covers 2-core, 3-core, and 4-core cables with an uninsulated full-size circuit protective conductor of tinned annealed copper and metallic screening. These cables are specifically designed for use in building voids, partitions and walls where there is a risk of damage or penetration from nails, screw fixings, and similar fasteners.
