ABC
East Energy Electrical Engineering Co., Ltd. specializes in the manufacturing of high-performance Aerial Bundled Conductors (ABC) with XLPE insulation, engineered for safe, reliable, and efficient overhead power transmission across urban, rural, and industrial sectors.
Our ABC cables are designed to replace traditional bare overhead conductors, offering enhanced safety, reduced installation space, and lower maintenance costs. They are widely used in low voltage (LV) distribution networks (0.6/1kV) and medium voltage (MV) systems (11kV / 33kV), complying with IEC 60502 and HD 626 standards.
XLPE Insulation: Cross-linked polyethylene provides excellent electrical properties, high thermal resistance (up to 90°C), and UV protection for long outdoor service life.
Compact Bundled Design: Phase conductors twisted around a neutral messenger or self-supporting design reduces installation space and pole loading.
Enhanced Safety: Fully insulated conductors minimize the risk of electrocution, short circuits, and wildlife-related outages.
Weather & UV Resistant: High-quality XLPE and HDPE materials resist moisture, salt spray, UV radiation, and temperature extremes (-40°C to +90°C).
Low Maintenance: Sealed insulation eliminates the need for tree trimming and reduces fault-causing contact with external elements.
Long Service Life: Designed for 25+ years of reliable operation in harsh outdoor environments.
