什麼是BS6622電纜？— 中壓交聯聚乙烯絕緣電力電纜技術指南
Introduction 簡介
BS6622 is the British Standard specification for single-core and multicore cables with extruded cross-linked polyethylene (XLPE) insulation for rated voltages from 6.35/11kV up to 19/33kV. These medium voltage (MV) cables are specifically designed for power distribution networks, underground installations, and cable ducting applications. The standard ensures consistent quality, safety, and performance across all compliant products.
According to technical data from Anhui Feichun Special Cable Co., Ltd., BS6622 cables are manufactured with Class 2 stranded copper conductors complying with IEC 60228/BS 6360, featuring extruded semi-conductive XLPE conductor screens with minimum thickness of 0.3mm and maximum resistivity not exceeding 500 Ω·m at 90°C.

根據安徽飛純特種電纜有限公司的技術資料，BS6622電纜採用符合IEC 60228/BS 6360標準的2類絞合銅導體製造，配備擠出式半導電XLPE導體屏蔽層，最小厚度0.3mm，90°C時最大電阻率不超過500 Ω·m。
Key Specifications 主要規格
Cable Construction 電纜結構
Armour Types 鎧裝類型
AWA (Aluminium Wire Armoured) — Used for single-core cables. Aluminium wire armour provides mechanical protection while maintaining non-magnetic properties, essential for AC single-core cables to prevent eddy current losses and excessive heating.
SWA (Steel Wire Armoured) — Used for multi-core cables. Galvanized steel wire armour offers superior mechanical protection and tensile strength for underground and direct burial installations.
AWA（鋁絲鎧裝）— 用於單芯電纜。鋁絲鎧裝提供機械保護，同時保持非磁性特性，這對於交流單芯電纜防止渦流損耗和過熱至關重要。
SWA（鋼絲鎧裝）— 用於多芯電纜。鍍鋅鋼絲鎧裝為地下和直埋安裝提供卓越的機械保護和抗拉強度。
Compliance Standards 符合標準
BS6622 cables are flame retardant according to IEC/EN 60332-1-2 (single cable vertical flame propagation test). Conductor construction complies with EN 60228 and BS 6360 for stranded copper conductors.
BS6622電纜符合IEC/EN 60332-1-2（單根電纜垂直火焰傳播試驗）阻燃標準。導體結構符合EN 60228和BS 6360絞合銅導體標準。
