Zhengheng Power’s business expands into photovoltaic modules

Against the backdrop of the booming development of the photovoltaic industry, Zhengheng Power has successfully partnered with a well-known new energy photovoltaic company in Chengdu to develop new photovoltaic equipment frame lock component products.
Facing the harsh outdoor environment, the quality and performance requirements for photovoltaic equipment components are also constantly increasing. In photovoltaic equipment, the frame lock component is a key part of the fastener, and its design and material selection are particularly critical. The product must have excellent corrosion resistance and impact resistance to ensure long-term stable operation and avoid equipment damage caused by environmental factors. or performance degradation.
Secondly, anti-loosening design is an indispensable part. Measures such as double-layer self-locking washers, serrated washers, locking nuts, etc. are required to effectively prevent loosening problems caused by factors such as climate change and ensure the stability of the equipment.
Furthermore, precise installation and positioning is also one of the important criteria when considering frame lock components of photovoltaic equipment, which facilitates quick and accurate assembly and positioning and improves construction efficiency.
In addition, the design principle of combining high strength with lightweight is equally important. By selecting high-strength materials and optimizing the structural design, the goals of large preload force, small size, and light weight are achieved, which helps reduce the overall equipment load and optimize system efficiency.
At the same time, in order to simplify the maintenance process and reduce operation and maintenance costs, the photovoltaic equipment frame lock assembly should be easy to install and maintain, and facilitate standardized operations and quick replacement.

This product adopts extrusion and cutting precision casting technology, which not only meets the standards of high-strength materials, but also achieves innovation on the original basis in terms of design optimization.
(1) Technical requirements:
1. High-strength material requirements: The chemical composition meets GB/T 3190 “Chemical Composition of Deformed Aluminum and Aluminum Alloys”; the material’s tensile strength is 260Mpa, the yield strength is 240Mpa, the elastic modulus is 69±5Gpa, and its mechanical properties meet GB 5237.1 “Aluminum” “Alloy Building Profiles Part 1 Base Material”, in which the elongation is not less than 8% and the fatigue strength is not less than 100Mpa;
2. Anti-corrosion and anti-rust requirements: The surface is made of ordinary silver-white anodized material and complies with the national standard GB 5237.2 “Anodic oxidation profiles for aluminum alloy construction profiles part 2″; the film thickness of the oxide film should not be less than AA15;
3. High-precision extrusion tolerance requirements: according to GB/T 6892-2015-high-precision grade;
(2) Design optimization:

1. Design the top mounting hole to the center – so that the steel rope is evenly stressed;
2. The original design weighs 67.2 grams/set, and the new design weighs 63.3 grams/set, saving about 4 grams of material per set;
3. Installation anti-falling design: The lower clamping block is embedded and cannot fall off by itself.
(3) Installation and use effects:

With the help of advanced mold design and intelligent production equipment, Zhengheng Dynamics has continuously improved its process flow and improved production efficiency and product quality. We will continue to be committed to technological innovation and process upgrading, constantly pursue higher quality casting products, and export more high-quality products to the new energy field!
