How to choose suitable PV Accessories?
PV Accessories are auxiliary components in photovoltaic power generation systems, which are of great significance to ensure the efficient operation, stability and safety of the system. Common photovol
• The elasticaccumulating accelerating mechanism for instant release realize the rapid making and breaking (13.8m/s), having no relationship with the speed of the operating handle,and increasing greatly the capability ofextinguishing electric arc.
• The sheu made of unsaturated polyester resin reinforced by glass fiber possesses excellent performance of flame resistant, dialectic performance, safe operation, resist carbonic performance and resist impact performance.
• Parallel double gap contact possesses self cleaning functions.
• All the contact materials are copper alloy plated with silver, and possess two separation contact surfaces.
• Large clearance of insulation.
• Be on "0", the products can lock the handle with three locks at the same time and thus can avoid error operation.
