For one of the important measures of shaft tower lightning protection: installing down conductor, this work is particularly important, but important currently as lightning protection
The down conductor of measure, always exists many contradictions, down conductor bury a little be in the corrosivity such as paddy field and salt-soda soil compared with
In strong soil, after operation in 3 ~ 5 years, being unearthed in downlead, that rust is easy between ground junction 30cm or so is disconnected, once rust breaks
Or corrosion is serious, pole tower ground resistance can be significantly greatly increased, operations staff needs to exert to check by base, tight for corroding
Weight situation is included in plan of major repair, needed replacing every 5 years or so, significantly increases operating cost.
In current existing technology: 1, down conductor buries a brush antirust paint, generally needs 1-2 brush primary, practical effect
Fruit is unsatisfactory, now with more on power transmission pole tower ground down lead；2, material is changed, replaces zinc-plated circle using copper material
Steel, it is at high cost and easily stolen although playing good rust-proof effect, do not implement in transmission line of electricity；3, increase and connect
Ground downlead quantity installs new down conductor, but this operating cost mistake additional at the ground line that corrosion is serious or rust is disconnected
