hl牌螺钉系列的超高压陶瓷电容已经广泛应用于送电、配电系统的电力设备和处理脉冲能量的设备中，如：功率补偿、限流、滤波、计量、储能以及分电压等产品中。电力系统的特殊*流、高电压、高频、处于室外环境 (-40°c到+60°c)、雷击、大电流等等，在恶劣环境，要求电容具有超强的稳定性，即变化率要小；同时，计量，分电压等产品要求高精密度，这对处于这种环境下的高压陶瓷电容器的局部放电量有着极为苛刻的要求：局放为3pc-50pc不等。
hl brand screw series ehv ceramic capacitors have been widely used in electrical equipment and the pulse energy equipment of power transmission and distribution systems, such as: power compensation, current limiting, filtering, metering, energy storage and sub-voltage products. the particularity of the power system are: ac, high voltage, high frequency, in the outdoor environment (-40°c to +60°c), lightning, high current, etc., capacitors are required to have superior stability in harsh environments, the rate of change is small; at the same time, metering, sub-voltage and other products requiring high precision, magnitude of partial discharge of high voltage ceramic capacitors in this environment has a very demanding requirements: pd from 3pc to 5pc.
