The Logic Behind Classifying Cold Shrink Cable Accessories By Voltage Rating

Different voltage levels correspond to different requirements for electrical field strength, insulation thickness, and dielectric structure. Low-voltage applications have less stringent requirements for insulation thickness and stress control design, but as the voltage increases, the electric field distribution and insulation shielding design inside the Cold Shrink Cable Accessories become more complex. Manufacturers must determine the appropriate material and structural parameters based on the voltage level to ensure that each type of cold-shrink accessory meets industry standards under specific voltage conditions.

For the same type of cold-shrink cable accessory, the voltage level also determines the insulation material thickness and shielding configuration, which in turn determines the product's adaptability to the electrical field during field installation. Product design typically uses major voltage levels (such as 1kV, 10kV, 35kV, etc.) as distinguishing nodes, with each node encompassing different wire diameter specifications.
