Wide door tensioned between two posts and method of spanning the width between two doorposts

摘要

The invention describes coated conductive elements of a type which are suitable for electric fencing applications and describes desirable characteristics of a coating. One described embodiment according to the invention comprises a coated conductive core; said coating, comprising at least one layer, being ultra-violet stable and flex-damage resistant as defined in the specification, the electric resistivity of said coating when measured radially exceeding 1300 mu OMEGA /cm, the coating being further characterised in that the product of its average thickness and dielectric strength is less than 8kV. Coatings may be applied,for example, to protect the core or to alter visibilty.
