LT Aerial bundled cables (simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. This contrasts with the traditional practice of using un-insulated conductors separated by air gaps. This variation of overhead power lines utilizes the same principles as bundled conductors, except that they are closer together to the point of touching but each conductor is surrounded by an insulating layer (except for the neutral line).
2 LV distribution lines.
Improved reliability in comparison with both bare conductor.
overhead systems and underground systems. Insulated conductors prevent accidental contact and supply can be maintained temporarily in the event of a suspension system collapse. Can be installed in a narrower right of way. Ease of erection and stringing, less labour intensive, less construction resources needed. Can stand in close proximity to trees / buildings and will not generate sparks if touched.
