High Voltage Underground Cable Installation Standards
High voltage underground cable installation typically involves direct burial in trenches, with installation depths depending on the cable voltage. For 3.3kV to 11kV cables, a minimum trench depth of 0.9 meters is required, while for 22kV to 33kV cables, a minimum depth of 1.05 meters is recommended. The trench should be partially filled with sand to protect the cable, with at least 50mm of sand between the cable and the trench bottom. In addition, proper cable protection using conduits or ducting is essential to prevent damage.

What Are SATA Cables Used For?
SATA cables (Serial Advanced Technology Attachment cables) are primarily used to connect storage devices such as hard drives, solid-state drives (SSDs), and optical drives (like DVD or Blu-ray drives) to a computer’s motherboard or host controller. These cables are a crucial component of modern computer systems, enabling data transfer between the storage devices and the rest of the system.

What is otg cable?
An OTG cable (short for On-The-Go cable) is a type of USB cable that allows devices, such as smartphones or tablets, to connect directly to other USB devices without the need for a computer. It essentially enables mobile devices to function like USB hosts, allowing them to read data, transfer files, or control peripheral devices like a mouse, keyboard, flash drive, or even another smartphone.

What is a Cat 5 Cable?
A Cat 5 cable, or Category 5 cable, is a type of twisted pair cable commonly used in networking and telecommunications. It was once the most popular type of Ethernet cable for local area networks (LANs), providing the necessary data transmission speeds for most networking needs. Though now largely replaced by newer standards like Cat 5e and Cat 6, Cat 5 cables are still used in some environments, particularly for older systems.

What is an optical cable？
An optical cable, also known as a fiber optic cable, is a type of cable that uses light to transmit data. Unlike traditional copper cables, which transmit electrical signals, optical cables send data in the form of light pulses through glass or plastic fibers. These cables are commonly used for high-speed data transmission over long distances, making them essential in modern communication networks, internet connections, and even in applications like home entertainment and medical equipment.

What Does an Ethernet Cable Do?
an Ethernet cable connects devices, transmits data, ensures reliability, and enhances security, playing an integral role in any network. Whether you're setting up a home network, expanding a business network, or connecting a gaming console, Ethernet cables remain a staple for wired communication, delivering fast, secure, and dependable connectivity.

What is a sata cable?
A SATA cable (Serial Advanced Technology Attachment) is a type of data cable used to connect storage devices like hard drives (HDDs), solid-state drives (SSDs), and optical drives (e.g., CD/DVD drives) to a motherboard or controller card in a computer. SATA cables have largely replaced the older PATA (Parallel ATA) cables due to their faster data transfer speeds, simpler design, and smaller connectors.

What Does Fiber Optic Cable Look Like?
Fiber optic cables are typically thin, flexible, and have a smooth outer appearance. The outer jacket is usually black, yellow, or orange, depending on the type of fiber (single-mode or multi-mode). When you hold a fiber optic cable, it feels lightweight and can easily bend without breaking. Inside, the core is made of glass or plastic fibers that are extremely small — around 8 to 10 microns in diameter for single-mode fiber and 50 to 100 microns for multi-mode fiber. Surrounding the core is a protective cladding layer, which may appear clear or slightly tinted, and a buffer coating that ensures the cable is more durable and flexible.

What Are Cable Powers?
The term "cable powers" generally refers to the electrical power transmission capacity of a cable, meaning how much electricity the cable can carry safely.

What is Fiber Optic Cable Made Of?
Fiber optic cables are primarily made of glass, specifically ultra-pure silica glass, which forms the core and cladding. The core carries the light signal, while the cladding surrounds the core and reflects the light back into the core to maintain signal integrity. A protective outer layer or buffer, often made of plastic, surrounds the cladding to shield the delicate glass fibers from damage.
