Analysis And Standardization Of The Coding System For The Bolt-type Structure Of Tension Clamps

Take the common bolted type strain clamp model NLD as an example: N stands for tension resistance, L refers to aluminum material, D is flip-chip structure, and the number 4 corresponds to the applicable wire cross-section of 300-400 square millimeters. However, NLD shows that this is dead end strain clamp, with a steel core cross-sectional area of 300 square millimeters and an outer layer of aluminum stranded wire of 40 square millimeters. When encountering models such as NLD-J, the J character indicates that this bolted dead end clamp is specially designed for insulated wires and needs to be matched with a special sealing structure.
