As early as 1955 it was determined in the Wisconsin Telephone Company that certain combinations of stainless and mild steel when used in conjunction with various pieces of buried hardware produce a condition which greatly accelerated the deterioration of the unit. A noteworthy example is the Load Coil Case. There are two locations where stainless steel is used on Load Coil Cases. Stainless steel studs are employed to secure the supporting hardware to the case for the cable entering the Load Coil. Stainless steel studs are also located on the bottom of the case. The cases are very well protected having several different layers of coating but nevertheless, these cases are being damaged.
