Ⅳ. Unique Design
1. Built-in stress control
As part of its design, the NKS Power 24kV heat shrink outdoor medium voltage cable termination includes a stress control system that ensures uniform distribution of the electric field. Therefore, it can effectively lower concentration within the electric field, enhance stability concerning electrical performance for the terminal itself, increase product life, and decrease failure risk.
2. Ensuring Uniform Distribution of Electric Field
With material formulation and structural design optimization, the NKS Power 24kV heat shrink outdoor medium voltage cable terminal can achieve a uniform electric field distribution. This would increase the electrical performance of the terminal and reduce partial discharge induced by uneven electric fields; hence an increase in the safety and reliability of power systems.
3. Compatible with Various Cables and Connection Methods
Made with different user needs in mind, this end works for both copper and aluminum wires and fits many ways of connecting like crimp ends and screw ends. This ease lets it be used often in many power setups, whether in new builds or as a boost to old wire systems.
