Overview of Voltage Classifications

Electric cables are classified into low, medium, and high voltage categories based on their voltage ratings, each designed for specific applications in power distribution and electrical systems. Low voltage cables, typically rated up to 1kV, are used for residential and light commercial wiring. Medium voltage cables, ranging from 1kV to 35kV, support industrial and utility distribution. High voltage cables, exceeding 35kV, are employed for long-distance power transmission. Jianyun Cable Co., based in Luoyang, China, offers a comprehensive range of cables across these categories, ensuring quality and reliability, as discussed in prior articles on AWG, XHHW vs. XLPE, and RW90 sunlight resistance.

Low Voltage Cables

Low voltage cables, rated up to 1kV (e.g., 220V, 380V, 600V), are designed for short-distance power distribution and control applications:

• Construction: Comprise copper or aluminum conductors with insulation like PVC or XLPE, and optional sheathing, similar to T90 or TW75 cables.
• Properties: Flexible, with temperature ratings from -40°C to 90°C, moderate moisture resistance, and limited UV resistance, requiring conduit in outdoor settings.
• Uses: Power household outlets, lighting, and low-voltage equipment in residential and commercial buildings, as explored in low voltage wire discussions.

These cables are cost-effective and easy to install, ideal for controlled environments.

Medium Voltage Cables

Medium voltage cables, rated from 1kV to 35kV (e.g., 10kV, 35kV), are engineered for industrial and utility power distribution:

• Construction: Feature copper or aluminum conductors, XLPE insulation, and additional layers like semiconductor shields and metallic screens for enhanced performance, akin to TR-XLPE cables.
• Properties: Rated from -40°C to 90°C, with high moisture and chemical resistance; some include protective jackets for direct burial, similar to RWU90.
• Uses: Distribute power in factories, substations, and underground utility networks, as discussed in medium voltage cable articles.

These cables balance efficiency and durability for moderate-distance power delivery.

High Voltage Cables

High voltage cables, rated above 35kV (e.g., 110kV, 220kV, 500kV), are designed for long-distance power transmission:

• Construction: Include complex structures with multiple layers, such as conductors, XLPE insulation, semiconductor layers, metallic shields, and robust jackets, to withstand high electrical stress.
• Properties: Operate from -40°C to 90°C, with superior moisture, UV, and chemical resistance, suitable for underground or submarine applications.
• Uses: Transmit power across regional grids, connecting power plants to cities, as noted in prior discussions on high voltage cable structures.

These cables are critical for efficient, high-capacity power transmission.
