Powder Coated Stainless Steel Busbars Laser Cut CNC Machined Parts For Power Systems
Specification
1. Material: Stainless Steel
High conductivity: 304/316 stainless steel is selected, with better conductivity than carbon steel and a 20% increase in current carrying capacity.
Corrosion resistance: Natural rust resistance, able to withstand humid, acidic and alkaline environments (suitable for coastal power stations or chemical scenes).
Mechanical strength: Tensile strength ≥ 520MPa, avoiding deformation under high current and ensuring long-term stability.
2. Process combination: Powder Coating+Laser Cutting
Powder coating
Insulation protection: Epoxy/polyester coating thickness of 80-120 μ m, insulation withstand voltage>5kV, blocking the risk of leakage.
Weather resistance: UV resistance, oxidation resistance, outdoor service life>15 years (traditional galvanizing only 5-8 years).
Aesthetic customization: Available in RAL color card color, indicating the company VI (such as red warning strip, gray industrial style).
Laser cutting
Precision molding: ± 0.1mm tolerance, ensuring seamless busbar splicing and reducing contact resistance.
Efficient processing: No need for mold opening, supports complex hole positions/irregular designs (such as heat dissipation holes, installation slots).
3. Core function: Arc Resistant
Electric arc hazard: Electric arcs are easily generated when the power system is short circuited or overloaded, causing fires or equipment damage.
Solution:
Stainless steel substrate+high temperature resistant powder coating (capable of withstanding instantaneous temperatures>300 ℃).
Laser cutting has smooth and burr free edges to avoid the formation of discharge points.
4. Application scenario: Power Systems
Typical equipment: distribution cabinets, substation bus ducts, wind turbines, data center UPS.
Security upgrade: insulation coating+arc protection
Energy efficiency optimization: Low resistance stainless steel reduces energy loss (compared to aluminum busbars, temperature rise is ↓ 15%).
Simplified maintenance: No need for galvanized layer peeling maintenance, extended cleaning cycle to 2 years.
