• ELV Construction and Acceptance

  • The ELV infrastructure construction project is required to meet high-concurrency network demands and industrial-grade security standards, ensuring 7×24 hours of stable operation for both production and office networks. Encompassing structured cabling, video surveillance, access control systems, and wireless AP coverage, the project spans multiple core production workshops and modern office areas across a vast construction footprint. It must be delivered on schedule to high standards without disrupting the plant's normal production operations, ultimately achieving seamless integration and smooth evolution between the ELV systems and the existing IT architecture.

  • Procurement Material Management and Supply Chain Assurance

    1

    Core cabling utilizes premium-brand twisted-pair cables and optical fibers. Prior to site entry, all materials must undergo strict verification of original factory certificates of compliance and anti-counterfeiting labels, thereby eliminating the risk of substandard cables entering the construction site.

    2

    Cabinets, cable trays, and auxiliary materials are subject to centralized procurement strictly in accordance with the BOM list. By optimizing logistics scheduling, the material delivery lead time is reduced by 15%, effectively ensuring the continuity of on-site construction.

    3

    A dedicated temporary site warehouse is established to implement classified and zoned storage with strict temperature and humidity control. Special protective measures are adopted for precision network equipment and moisture-sensitive fiber optic splicing trays, effectively reducing the material loss rate.

  • On-site Construction and Standardized Cabling

    Cabling Installation Workmanship and Quality Control

    Separation of high and low voltage

    Strictly adhere to the specification that the parallel spacing between high and low voltage cable trays must exceed 30cm. Metallic partitions are installed at crossing points for shielding, thoroughly eliminating the hidden risks of electromagnetic interference (EMI) at the physical layer.

    Fully enclosed conduit

    For conduit installation within the ceiling plenum, fully enclosed galvanized steel conduits are adopted. Dedicated conduit benders are utilized at bends to strictly ensure the required bending radius, thereby guaranteeing smooth and unobstructed cable replacement during future maintenance.

    Precise Traction

    During the cable pulling process, tension and bending radius (not less than 8 times the outer diameter of the cable) are strictly controlled to avoid damage to internal conductors or rupture of the insulation layer.

    Flexible Tying

    Appropriate slack length is reserved at both the cabinet end and the workstation end. Grouped bundling is performed using Velcro straps, while traditional plastic cable ties are strictly prohibited to prevent crushing or damaging the cable outer jacket.

  • Labeling, Documentation Management, and Standardized Delivery

    Section image

    Dual-end machine-printed labeling system

    Waterproof and tear-resistant machine-printed labels: All information panels, patch panel ports, and both ends of cables shall be affixed with waterproof and tear-resistant machine-printed labels.

    Section image

    Synchronous update of as-built drawings

    Precise CAD Recording: During the construction process, CAD technology is utilized to accurately record the routing of concealed conduits and pipelines, the actual installed locations of equipment, and cable pathways.

    Section image

    Dual-track archiving of process documentation

    Dual-track parallelism of electronic and hard-copy formats: Process documentation, including material inspection submissions, concealed works acceptance records, and test reports, shall be archived in both electronic and hard-copy formats.

  • Equipment Installation and Testing & Acceptance

  • Core Equipment Installation and System Commissioning

    Meticulous Installation

    Based on the detailed design drawings, complete the precise placement of core server room equipment, front-end sensing devices, and transmission links. Emphasize strict control over cabinet cable management, labeling, power redundancy, and lightning protection grounding to ensure high availability of the hardware infrastructure.

  • Comprehensive Commissioning

    Execute a three-tier commissioning process of "Single-Unit → Subsystem → Total Integration"

    • Basic Commissioning: Complete device power-on self-test, firmware upgrade, and IP address planning to ensure both physical and network links are operational.

    • Functional Commissioning: Conduct item-by-item verification of core functions such as video surveillance, access control & alarm, and BA (Building Automation) control, and calibrate device parameters to their optimal state.

    • Integrated Linkage Commissioning: Break down data barriers between weak current subsystems and validate cross-system linkage strategies (e.g., fire alarm triggering access release and video pop-ups) to ensure a closed-loop system logic.
