Low-price traps: Some small manufacturers quote prices more than 30% below the market price, but actually use brass/steel instead of T2 copper, use hollow grounding wires, and reduce plate thickness. This results in a high failure rate during operation and losses far exceeding the savings from purchase price.
2. Certificate fraud: Some manufacturers purchase reports from private testing agencies or submit products for testing using the 90K temperature rise standard. In reality, mass-produced products exceed temperature rise limits. It is necessary to rely on 3C Beijing/provincial and municipal quality inspection center witnessed reports.
3. Protection rating deviations: Some manufacturers claim IP65/IP66, but the actual level only reaches IP54. A third-party protection rating test report should be requested.
4. Lack of after-sales service: Some small manufacturers do not supply spare parts after the project ends, and responses to faults during the warranty period are not timely. It is necessary to choose manufacturers with physical factories and long-term business history.
5. Parameter deviations: Some manufacturers have discrepancies in current ratings and short-circuit withstand capability, resulting in high overload risk during actual operation. Core parameters should be clearly specified in the contract, and sampling inspection clauses should be agreed upon.
