Aerial cable systems primarily consist of tree wire conductors. The covered conductors of aerial cable systems are considered bare conductors for electrical insulation requirements. It is more suitable for long runs where there are few transformers and spurs lines. It is commonly strung together with LV cable on the same poles. The use of aerial cable systems to skid logs has not been widely introduced. It eliminates the need for multiple-duct underground construction and its numerous associated problems, such as; extreme high cost conflicts with other underground utilities, and extended vehicle traffic tie-ups during initial construction and future expansion. The advantages of an aerial cable system are (1) the cable cannot be accidentally dug up, and (2) most of the utility cables are on transmission lines, far off the ground and only accessible by trained professionals.
