Sediver insulators are delivered packed in wooden crates on pallets. This packing is designed for long-term storage; however, since wood is sensitive to humidity, if the insulators are to be stored for a long period of time it is recommended to store the crates in a ventilated area.

The wood may darken with time, but will keep its mechanical strength.

If for some reason the insulators have been stored for a long period of time in a confined & humid atmosphere, white traces can appear on the metal fittings. This deposit - which is simply zinc oxide - can be removed by simple brushing and/or washing of the metal parts. This deposit is totally harmless and does not affect the insulators' behaviour.

When the insulators are stored in a dry atmosphere, it may become possible to rotate the pin by a few degrees - with a clicking noise. This is due to a slight shrinkage of the cement which has no consequence on the mechanical characteristics of the insulators. This phenomenon dissapears once the insulators are under load.
