Definition:  An item consisting of a coil of insulating tubing for the purpose of containing a column of liquid. This liquid is used to cool an element at a high electrical potential from ground (such as the plate of an electron tube or a high wattage resistor), and the column is of such length as to provide resistance sufficient to reduce the leakage of current between the element at high potential and the low-potential cooling system to a negligible value.

Description:  1. (Electrical) An item made of nonconductive material, such as natural occuring mineral mica, vitrified inorganic materials produced by means of heat (ceramic materials), or material which has been electrically rated by government or industry standards or specifications. It is used to support or separate conductors and is specifically designed to prevent any undesirable flow of current between conductors and/or other objects.
