Technical characteristics and advantages

1. In order to make the installation of the insulator more stable, the upper and lower ends of the insulator adopt double hole structure, and the upper and lower ends are fastened by two stainless steel screws.

2. The isolating switch moving contact conductor is fixed through the stud, the stud structure is extended, the double nut lock is more stable, the clamping force is strengthened, the contact is better, and the conductivity is improved.

3. The design of the mechanism is made of stainless steel, which is anti-corrosive and durable, and it is combined with stainless steel spring to improve the mechanical performance.

4. Adopt stainless steel 304 base, replace the iron plate + galvanized base, more environmentally friendly, time reduction point, tensile, torsion enhancement, wind and rain resistance, corrosion resistance.

5. The silver plating layer of the contact part is thickened, and the electrical performance of the conductive part is enhanced by tin plating.

Innovation points:

1. Double-hole structure of insulators and double nuts reinforced by studs are locked. The vibration generated during the operation of the isolator will not loosen the dynamic and static contacts and insulators, and the mechanical performance is stable.

2. The installation size of the isolating switch operation mechanism should be uniform, anti-corrosion and durable, and interchangeable.

3. The production and processing efficiency of the base is improved, and the production process is more environmentally friendly. The material is 304 4mm, with enhanced tensile and torsion resistance, wind and rain resistance and corrosion resistance.

4. Contact clamping force is enhanced to improve mechanical and electrical properties.

5. The thickness of the coating enhances the electrical conductivity of the contact and improves the corrosion resistance.
