"GB/T 3334-1999 Cable paper dielectric loss tangent (tg δ) test method (bridge method) " stipulates the test method for determining the cable paper dielectric loss tangent (tg δ) by bridge method. The standard covers the test principle, equipment, sample preparation, operation steps and result calculation. The value of tg δ of cable paper is accurately obtained through bridge testing, which provides a scientific and unified test standard for evaluating the insulation performance of cable paper and controlling the mass of products.
