The ceramic guy strain insulator used in the stay wire is called as the stay insulator and is usually of porcelain and is so designed that in case of breakage of the insulator the guy-wire will not fall to the ground.įunctions of porcelain guy strain insulator:ġ. The color is brown, gray or white.įor low voltage lines, the ceramic guy strain insulator is to be insulated from ground at a height. Porcelain stay insulator is mainly used on the guy wire structure to balance the tension strength and also provide the insulating. WILHEIM PETERS.What is porcelain stay insulator or ceramic guy strain insulator?Ĭeramic guy stain insulator is an insulator generally with elongated shape, and the porcelain stay insulator has two transverse holes or slots. In other words, it is the lowest for the M4 type radiator for which therefore the voltage drop on the guy chain is very marked. However, this action will be so much lower, the more steeply the voltage on the mast declines to the base or footing. However, in reality, the gradient is slightly less severe for the reason that, as a result of influence actions potentials are induced from the live mast through capacitances existing between the mast and the guy cable sections in the lower sections of the guys. In a great many practical cases, equality of these capacitances must be figured with. The voltage gradient in the neighborhood of the mast becomes so much steeper and marked, and hence the voltage strain of the insulators in the vicinity of the mast so much greater, the smaller the ratio of C is to c.
