4KN uncapped line post insulator
4KN uncapped line post insulator usually is used for below 132KV transmission line. Line post insulator as same as pin type insulator, they are all used to fix and support wire or cable. One side is connected to wire and support, another side with fitting is connected to cross arm. But the different with pin post insulator is that, line post insulator is non punctured insulator,pin post insulator is punctured type insulator.
Line post insulator have two cementing methods, they are capped insulator and uncapped insulator.Today, we should know what is the 4KN uncapped line post insulator.
4KN uncapped line post insulator
Line post insulator's stud is long stud or short stud. Among them, long stud is used to wood cross arm ,and short is used to iron cross arm. They are all the composite cross arm insulator.
The focus on the 4KN uncapped line post insulator is the connection for stud and porcelain. 4KN uncapped line post insulator the end fitting is cemented in porcelain part, but capped line post insulator is cemented outside of porcelain part. 4KN uncapped line post insulator is usually used to Africa countries.
Maybe 4KN uncapped line post insulator is according to the ANSI standard to classify. Because according to specific mechanical failing load, ANSI standard products include 4KN, 6KN, 8KN, 10KN, 12.5KN, so, the 4KN uncapped line post insulator is ANSI 4KN line post insulator.
