Product Overview
The FPQ-10/4T20 composite pin insulator has a rated voltage of 10 kV and a rated mechanical load of 4 kN, and is used for pin-type insulation support on high-voltage lines.
The insulator is suitable for high-voltage line facilities. It offers excellent hydrophobicity, ageing resistance, tracking resistance and erosion resistance, together with very high tensile and bending strength. It features high mechanical strength, good impact, vibration and anti-brittle performance, and is light in weight and easy to install. Its top and bottom mounting dimensions are identical to those of the corresponding porcelain pin insulators, so the two can be used interchangeably. The product withstands bending loads of 5-12.5 kN. As a pin-type insulation support widely used on 10 kV distribution lines, the FPQ-10/4T20 composite pin insulator directly replaces porcelain pin insulators of the same mounting dimensions without any modification to the cross-arm.
Type Designation
In the type designation, F stands for the composite insulating material (silicone rubber housing + epoxy resin core rod), P for the pin-type construction, and Q for the ball-and-socket coupling. The figure 10 before the slash indicates the rated voltage of 10 kV, the figure 4 after the slash the rated mechanical load of 4 kN, and the suffix T20 the steel cross-arm mounting structure together with the design serial number. This model has a structural height of 215 mm, a minimum nominal creepage distance of 300 mm and a lightning impulse withstand voltage (peak) of 75 kV; it is intended for pin-type support on 10 kV distribution lines and is interchangeable with porcelain pin insulators of the same mounting dimensions. The FPQ-10/4T20 composite pin insulator is moulded integrally from a silicone rubber housing and an epoxy-glass-fibre core rod, featuring compact dimensions and direct mounting on steel cross-arms.
