Abstract

The invention relates to a material formula for an insulating layer of a cable with low dielectric loss. The formula contains the following ingredients in percentage by mass: 2-8% of titanium white, 3-10% of white carbon black, 12-16% of paraffin, 10-12% of stearic acid, 5-8% of spray carbon black, 7-14% of aluminum hydroxide and 35-45% of resin. The formula has the advantages of reasonable material proportion, low cost and the like and has the function of lowering the dielectric loss of the cable, the utilization ratio of energy is increased, and a guarantee is provided for the normal use of mechanical equipment, communication and the like.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a low dielectric loss cable insulation layer material formula. Background technique [0002] Dielectric loss refers to the energy loss inside the insulating material due to the hysteresis effect of dielectric conductance and dielectric polarization under the action of an electric field, also called dielectric loss, or dielectric loss for short. Under the action of the alternating electric field, the complementary angle δ of the included angle (power factor angle Φ) between the current phasor and the voltage phasor flowing in the dielectric is called the dielectric loss angle. Dielectric loss and heat consumption consume energy and may cause thermal breakdown of the dielectric, which not only causes energy loss and reduces energy utilization, but also easily causes short circuits, damages equipment and disrupts communications. Therefore, in the electrical insulation t...
