■  Product Overview

35KV high-voltage SVG outdoor starting resistor SVG starting resistor is a type of starting resistor used in high-voltage direct current transmission systems. It serves as a reactive power compensation device to supplement the reactive power consumed in the power grid, thereby reducing energy loss in the power lines or transformers and helping to improve the quality of the power grid. Due to the fact that high-voltage direct current transmission systems are installed outdoors, SVG starting resistors are also used outdoors. In existing technology, ceramic tubes have insulation and sealing properties, so ceramic tubes are often used as resistance tubes for SVG starting resistors, and resistance wires are then placed inside the resistance tubes.

■  Functional Features

SVG startup resistor, with the resistance wire set inside the ceramic tube, filled with insulation filler between the inner wall of the ceramic tube and the resistance wire, and epoxy resin poured on the outer walls of both ends of the ceramic tube; Epoxy resin is a high thermal conductivity polymer, which can be poured onto the outer wall of ceramic tubes to improve their heat dissipation performance and impact resistance flexibility, thereby improving the electrical stability and anti rupture performance of resistors; In addition, epoxy resin further seals the resistor as a whole, reducing the impact of current harmonics on the transmission system and improving its stability.
