Wolun Polymer Lightning Arresters are manufactured to offer optimum protection to distribution equipment such as transformers and similar assets against the damaging lightning effects and similar operational conditions. These arresters perform their task with high-end improvement and fidelity towards surge switching and medium voltage networks. Maintenance of service safety for both underground and overheard setups is offered without any trouble on exposure in the outdoors for long durations. Going through precision tests have made Wolun arresters more durable & reliable.
