Design, manufacturing and inspection standards
All equipment and spare parts in the contract, including all accessories and equipment obtained by the Seller from a third party, shall comply with the relevant domestic and foreign standards of the latest version except the technical parameters and requirements specified in this article.
Product structure, technology and advanced description
Our company focuses on product design, production, inspection, installation and debugging of each detail of the process, will ensure that the equipment can meet: normal operation, inspection, maintenance operation.
1 housing
1.1 Material selection and Production:
(1) Cabinet door panel, side panel, roof and internal partition plate selection of 1.5-2.0mm thick high quality cold rolled steel plate, CNC machine shear plate, punching and bending molding, the surface of the advanced assembly line spray (or spray paint) process, the regular color of the finished product is high-grade industrial equipment RAL7032/ fine wrinkles gray (according to the requirements of other colors), Anti-glare and excellent corrosion and oxidation resistance.
(2) Follow the standardized design concept, size customized according to user requirements, can meet all kinds of circuit design requirements; The compact internal structure of the cabinet greatly saves the floor area.
(3) convenient installation and maintenance: a, high strength box body, easy handling: the whole cabinet structure is simple, convenient assembly, high precision, good mechanical strength, not easy to deformation when handling. B. Large wiring space: large cable outlet space ensures sufficient space for cable installation and maintenance, which greatly facilitates on-site operation and maintenance; Bolted removable bottom plate is installed at the bottom of the cabinet, equipped with cable sheath, which brings great convenience to site installation.
(4) Design with full consideration of safety:
Comprehensive and reliable grounding:
* Power distribution boxes are equipped with reliable ground terminals, which are connected to the ground bar with fastening screws or bolts. Independent ground bar. Earthing connection points marked with clearly visible earthing symbols;
1.2 Secondary Loop
(1) The main components of the secondary loop (such as intelligent instrument, reactive power compensation controller, etc.) shall be selected according to customers' drawings, and other unspecified general components shall be selected according to our company's conventional design and high-quality brand products. The measuring instrument and controller device are firmly and reliably installed, with anti-vibration measures, and will not affect its normal work and performance due to vibration during normal operation or transportation.
(2) The internal wires of all cabinets are equipped with high-quality 450V/750V xLPE insulated multi-strand copper core wires (except for the watt hour meter wires), and there is no joint in the middle of the wires. The cross sections of the control loop and voltage loop are 1.5mm2 and the current loop is 2.5mm2. (3) All secondary wire ends are connected with needle or lug with rubber sleeve to improve reliability.
