15-24KV ceramic pin type insulator
The description of 15-24KV ceramic pin type insulator:
Distribution ceramic pin insulator is one type of ceramic insulator, and it is composed by one or several ceramic parts and all the ceramic parts are connected by cement. Ceramic pin insulators are used on distribution lines and their function is to support conductor and insulate against ground. Ceramic pin insulator is installed on cross arm of poles by spindle.

Crossarm for 15-24KV ceramic pin type insulator:
Pin insulator can be fixed on wooden cross arm or steel cross arm. Wooden cross arm need the spindle has longer stalk and longer thread. Steel cross arm need the spindle has smaller stalk and smaller shank.
The 15-24KV ceramic pin insulator applied voltage:
The applied voltage of pin insulator: 6KV, 10KV, 11KV, 12KV, 15KV, 22KV, 24KV, 25KV, 33KV, 35KV, 36KV,11kv, 22kv, 33kv and others of the voltage mean rated voltage, but 12KV, 24KV and 36KV means system voltage. Of cause, 15-24KV ceramic pin type insulator means the pin type insulator classified by system voltage.
The puncture voltage of ceramic pin insulator:
15-24KV ceramic pin type insulator is puncture type insulator, and in order to avoid puncture in service, the puncture voltage of the pin insulator should be higher than flashover voltage.
Orient china’s aim is to offer to our customers the opportunity to purchase high quality branded high voltage insulator at competitive prices, offering a wide range of complimentary insulator products, in most global standards, from stock with the associated technical support, spares and service.
