Battery and Electrolytic Insulators

INSULATORS BATTERY AND ELECTROLYTIC These insulators are used to support tanks and jars for storage batteries and electrolytic cells to prevent grounding. They are usually porcelain insulators similar in construction to pin type insulators and sometimes have two or three petticoats for high voltage batteries. They are much larger in diameter as compared to their height than ordinary pin type insulators this feature providing larger bearing surface. Very often a wooden tray or supporting framework is built under the ceil and this tray rests on the insulators. Where storage batteries are used to provide a stationary rather high voltage source of energy glass jars are often used to enclose the individual cells. With a considerable number of plates in the jar it is quite heavy and therefore a uniform bearing surface must be provided. The glass jar bottoms are frequently not exactly even, so that it is necessary to rest the jars in a shallow tray filled with fine sand. The sand also serves the purpose of catching any moisture and electrolyte that may have spilled out. The tray is supported on the insulators having one at each corner. For large tanks they are occasionally placed at equal intervals under the long sides instead of at corners only.
