Why Do Companies Need a Large Amount of Cables?

Cables are used to transmit electricity, signals, or data, serving as the backbone of many industries. They can be high voltage cables (e.g., HT overhead lines, 11kV–400kV), low voltage cables (e.g., 14-2 NM-B, 230V), control wires (e.g., 24V, as discussed earlier), or communication cables (e.g., fiber optics). Companies need large amounts of cables for several reasons:

• Power Transmission and Distribution: Cables deliver electricity from power plants to consumers, such as HT and LT overhead lines (previously discussed) for long-distance transmission and local distribution.
• Signal and Data Transmission: Cables like fiber optics or control wires transmit control signals or high-speed data, common in automation and communication industries.
• Equipment Connectivity and Operations: Cables connect devices, machinery, and systems, ensuring smooth industrial processes or building operations, such as solar cables (4mm²/6mm², previously discussed) linking PV panels to inverters.
• Safety and Compliance: Using standards-compliant cables (e.g., IEC 60227, IEC 61730) ensures safety and regulatory compliance, especially in regions with strict fire safety requirements (e.g., Saudi Arabia’s SASO standards).

Cables are like a company’s “circulatory system”—they transport the “lifeblood” (electricity, data) to keep the entire “body” (operations) functioning.

What Types of Companies Use a Large Amount of Cables?

Various industries rely on large amounts of cables due to their operational needs. The table below summarizes the main types and their cable usage:

Utility Companies: Such as national grids, they use extensive HT (11kV–400kV) and LT (230V–400V) overhead lines (ACSR, ABC, previously discussed) for power transmission and distribution, spanning hundreds of kilometers.

Telecommunication Companies: Companies like AT&T use fiber optic cables for high-speed data transmission, supporting 5G networks and broadband, particularly in smart city projects like Saudi Arabia’s NEOM (previously mentioned).

Construction Companies: They wire residential and commercial buildings with cables like 14-2 NM-B or 2.5 mm², including control wires, to power lighting, HVAC, and security systems.

Renewable Energy Companies: Solar companies in Saudi Arabia use 4mm²/6mm² solar cables to connect PV panels to inverters (as discussed), supporting large-scale renewable energy projects.

Manufacturing and Industrial Companies: Factories use control wires (24V, previously discussed) and power cables to supply automated equipment and production lines, such as robotics in automotive plants.

Railway and Transportation Companies: Companies like Amtrak use overhead catenary cables to power electric trains and control wires for signaling systems, ensuring safe operations.

Data Centers: Operators like Google use vast amounts of fiber optic and power cables to support servers and high-speed data transmission for cloud services.

These companies are like “city planners”—cables are their “road networks,” connecting and supporting various “buildings” (business functions).

Specific Examples and Applications

Here are specific examples illustrating how different companies use large amounts of cables and the importance of cable management (previously discussed):

• Utility Companies: A utility company might need 500 km of ACSR cables to build a 132kV HT overhead line, connecting a wind farm to an urban grid, ensuring efficient long-distance transmission (losses of 1–2%, as discussed).
• Telecommunication Companies: In Saudi Arabia’s NEOM project, telecom companies might deploy thousands of kilometers of fiber optic cables to support smart city infrastructure, ensuring high-speed data and low latency.
• Construction Companies: Building a 30-story commercial structure might require thousands of meters of 2.5 mm² cables and control wires for lighting, elevators, and security systems, managed with cable trays and conduits (as discussed).
• Renewable Energy Companies: A Saudi solar project might use thousands of meters of 6mm² solar cables to connect tens of thousands of PV panels, ensuring UV resistance and minimal voltage drop (<3%, as discussed).
• Manufacturing Companies: An automotive factory might use hundreds of meters of 24V control wires to connect PLCs and robots, using cable trays to manage lines and prevent interference (EMI, as discussed).

Importance of Cable Management: These companies rely on cable management solutions (e.g., trays, conduits, ties) to organize cables, ensuring safety (avoiding bare wire risks), reducing interference (e.g., separating low and high voltage lines, as discussed), and easing maintenance. Compliance with standards (e.g., IEC 60332 for fire safety) is critical, especially in high-temperature regions like Saudi Arabia.

Cables are like a company’s “lifelines”—they support critical operations, and effective cable management ensures these “lifelines” don’t become a chaotic “spiderweb.”

Conclusion

Companies using large amounts of cables include utility companies (HT/LT overhead lines), telecommunication companies (fiber optics), construction companies (14-2 NM-B), renewable energy companies (solar cables), manufacturing and industrial companies (control wires), railway and transportation companies (catenary cables), and data centers (fiber optic, power cables). They use cables for power, signal, and data transmission, supporting core functions like transmission, communication, and automation. Examples show cables must meet standards (e.g., IEC 60227, IEC 61730) and be managed effectively (e.g., using trays, ties) to ensure safety and efficiency. Cables are foundational to these companies’ operations, and their management directly impacts business success.
