(A), the product delivery process services
1, delivery locations and models, specifications, quantities are demand-side fax or phone call, the company responsible for the free transport demand side, the designated place. Not have reached their destination, because of the way place packaging, cable tray, etc. causes the quality of accidents, the economic losses caused by my company.
2, cable installation, construction process and the unclear situation encountered questions can phone, instantly answer. The scene when necessary guidance, training (the city 3 hours, 6 hours in the province, outside the province 24 hours).
3, the establishment of user files, save the traceability data, test reports, technical information and original records; meet user requests.
4, due to design changes caused by the user specifications, type, quantity changes, I will respond positively "radical user anxious" to ensure a smooth construction project.
(B), on-site construction services
Free to send our service personnel on site, empowered to deal with the scene of all technology, quality and business issues; on-site service personnel of all acts, our company and responsibility. Field service personnel have the following conditions:
① Construction party to comply with the rules and regulations.
② have a strong sense of responsibility and hard work and good health, and can adapt to on-site working conditions.
③ able to grasp the cable properties, and structure of knowledge, kept informed about the installation and construction methods, and debugging considerations.
④ rich field experience and skills.
⑤ ability to coordinate the construction side, or to correct irregularities that may exist in operating behavior.
(C), training services
According to demand-side request, use telephone, fax, letters, etc. to contact the designated area on demand side, time and content of free training services. Generally include: product performance, use, structure, approximate diameter, weight, nominal thickness, ampacity, conductor resistance rate of conversion, elastic modulus, expansion coefficient, cable laying, installation notes, carrying capacity of cables in different environments such as knowledge guidance, and provide all the applications in line with national standards information.
(D), Technical Services
