    Automatic Reclosing Switch

    The LRW series automatic circuit reclosers can use on overhead distribution lines as well as distribution substation applications for all voltage classes 11kV up to 38kV at 50/60HZ power system.and its rated current can reach 1250A.
    The LRW series automatic circuit reclosers integrates the functions of control, protection, measurement, communication, fault detection, on-line monitoring of closing or opening.

    It has the following product structure features:

    1.The box shell is made of high-quality stainless steel or ordinary steel plate by antirust treatment process and then spraying ultraviolet resistant varnish.

    2. The insulation part is made of epoxy resin and silicone rubber composite insulation material, with high insulation grade and strong anti pollution ability. There is no transformer oil and sulfur hexafluoride gas in the tank, meeting the requirements of oil-free transformation and environmental protection.

    3. The operating mechanism is a spring operating mechanism, with manual and electric modes. The design of unique buffer device, excellent performance, small rebound, low noise.

    4. The vacuum interrupter adopts special stainless steel brazing technology, which is stable and reliable with low air leakage rate. Advanced ceramic metallization technology ensures the air tightness of products

    5. The CT is made of high-quality magnetic conducting material and composite insulation of epoxy resin and silicone rubber.

    6. According to the user's needs, it can cooperate with the corresponding controller to form auto recloser and sectionalizer, which is the ideal equipment to realize the distribution network automation.

    ADVANTAGES
    1.Modular design

    2.Compact and lightweight,easily installed on poles or in substations.

    3.Maintenance free throughout life.

    4.Highly resistant to ozone, oxygen, moisture, contamination and ultraviolet light.

    5.Adapt to adverse weather conditions and dirty environment.
