CAP AND PIN TYPE SUSPENSION INSULATORS
TOUGHENED GLASS SUSPENSION INSULATORS
IEC Ceramic station post insulator C10-1425, C12.5-1425 made by LIFENG INSULATORS in China is on good quality and under severe test. Station post insulator which is applied on high voltage substations need high quality since it is big and Each IEC Ceramic station post insulator C10-1425, C12.5-1425 should have done strict test under standard confirm its good quality.
IEC Ceramic station post insulator C10-1425, C12.5-1425 end fittings for high voltage use should be hot dip galvanized. After galvanizing, the station post insulator can be antirust, and have can be used for a long time. Normally the end fittings of IEC ceramic solid core insulator C10-1425, C12.5-1425 is cast iron type like other fitting assembled for line insulators. After casting, it will be tapped to make some thread in order to assemble with other parts.
IEC60273 has many requirement for high voltage IEC Ceramic station post insulator C10-1425, C12.5-1425, such as the dimensional requirement, test and inspection requirement, tolerance requirement, and so on, it also has detailed parameters for all of IEC standard station post insulator On IEC60273.
Except high voltage IEC Ceramic station post insulator C10-1425,C12.5-1425, C4-1425, C6-1050, C8-1050, C16-1050, C20-1050 are in the same types. Main parameter is as follows:
Cantilever strength: 4KN, 6KN, 8KN, 10KN, 12.5KN, 16KN, 20KN
Lightning impulse withstand voltage: 1425KV
Switch impulse withstand voltage wet: 950
Height of insulator: 3150mm
Creepage distance: 5600mm, 7800mm
Fixing diameter of end fitting hole: 127, 225, 254 ,275 300,325 or 356mm
Each IEC Ceramic station post insulator C10-1425, C12.5-1425 is under high quality control in LIFENG China, we will do routine test for each piece of post insulator and sample test for the batch of each order. We supply insulator picture and insulator test report for the IEC porcelain station post insulator we supplied and we also supply packing detail photos to the customer. If you also interested in 15-24KV ceramic pin type insulator, distribution line pin insulator ANSI 55-3, 55-4, 55-5 or any other item of our products, please don't hesitate to inquire us.
