What Happens If The Distance Between The Wedge-shaped Tension Clamp And The Tower Material Is Insufficient?

The proximity of dead end clamp for abc cable to the tower material directly affects the redistribution of the external electric field, especially in high-voltage lines. If the distance between fungsi dead end clamp and the tower material is too close, the local electric field intensity may accumulate, forming a channel that is easy to start an arc or discharge. This phenomenon must be analyzed and checked in power line design according to the design principle of preventing localized high electrical stress. During the design phase, simulations and actual measurements should be conducted in conjunction with structural assembly and insulator string configuration to observe the impact of spacing on the electric field distribution.

During installation, measuring the actual gap between the clamp dead end tower and the tower material and comparing it with the design value is one of the standards for judging whether a discharge channel may be generated. If the actual gap is too small, adverse environments such as humidity, rain, and snow may enhance local ionization conditions, thereby promoting the formation of discharge channels.
