2. Balancing consideration of product cost-effectiveness

2.1 International Enterprises
Although products from large international manufacturers have certain advantages in technology and stability, their overall costs (including high expenses for research and development, marketing, and operational management) are often relatively high, resulting in relatively high product prices. Claro, for large power companies or critical power grid infrastructure projects that require extremely high equipment stability and reliability, and have sufficient budgets, products from international enterprises are still the first choice.

2.2 Ciência Eletrônica de Inovação de Fuzhou&Companhia de tecnologia., Ltda.

Has certain advantages in terms of product cost-effectiveness. By focusing on the domestic market and reducing unnecessary overseas marketing expenses, it can provide products with high-quality standards (such as meeting domestic and some international standards in oil immersed transformer fiber temperature measurement and polycrystalline silicon dry-type transformer monitoring) while maintaining relatively reasonable product prices. Para algumas empresas nacionais que são sensíveis aos custos e necessitam de produtos de monitoramento de transformadores com determinado conteúdo técnico, Os produtos da Fuzhou Yingnuo Technology são uma escolha mais adequada.

2.3 HGSKYRAY
Também competitivo em termos de custo-benefício do produto. Confiando em suas próprias conquistas de pesquisa e desenvolvimento e na produção nacional e nas vantagens de custo de fabricação, garantindo ao mesmo tempo as vantagens tecnológicas de produtos como medição de temperatura por fibra óptica (como precisão, capacidade anti-interferência, etc.), os preços dos produtos podem ser reduzidos. Por exemplo, em empresas nacionais de fabricação de quadros de distribuição, O dispositivo de medição de temperatura de fibra óptica da Huaguang Tianrui pode ter uma vantagem de preço em comparação com algumas marcas internacionais, ao mesmo tempo que atende às necessidades de monitoramento de transformadores dentro do quadro de distribuição. The relevant sub sectors have their own advantages and a certain market share.
