Glass Insulator 40kn High Temperature Suspension Disc Type

Product DescriptionEach unit is constructed of a ceramic or glass disc with a metal cap and pin cemented to opposite sides. To make defective units obvious, glass units are designed so that an overvoltage causes a puncture arc through the glass instead of a flashover. The glass is heat-treated so it shatters, making the damaged unit visible. However the mechanical strength of the unit is unchanged, so the insulator string stays together.Product ParametersTechnical Date  TypeDiameter(mm)Height(mm)Creepage Distance(mm)SML(kN)Mechanical Routine Test(kN)Socket coupling(mm)Wet Power Frequency Withstand Voltage(kV)17811018540201125U40BDry lightning impulse withstand voltage(kV)Impulse Puncture Voltage(P.U)Power Frequency Puncture Voltage(kV)Radio Influence Voltage(μv)Corona visual test(kV)Power frequency electric arc voltage(kA)Net weight per unit(kg)502.8905018/220.12s/20kA2.1    Company ProfileFactory DirectWuhan Line Power transmission and transformation co., LTD.
