YJHLV cables are widely used in power transmission and distribution systems and industrial fields. How do you choose the right specifications for your project? Below, we'll provide a detailed introduction to the specifications and characteristics of YJHLV cables.
I. Model Introduction
1. Conductor Material: YJHLV cables typically use copper or aluminum as conductors. Copper conductors have excellent conductivity and corrosion resistance, making them popular in high-load and long-distance transmission lines. Aluminum conductors are relatively lightweight, making them suitable for long-distance suspension applications and offering lower costs.
2. Insulation Material: YJHLV cables typically use cross-linked polyethylene (XLPE) or cross-linked polyvinyl chloride (XL PVC) as insulation. XLPE insulation offers excellent electrical performance and heat resistance, making it suitable for high-temperature environments. XL PVC insulation is suitable for general use and offers a lower cost.
3. Number of Cores: YJHLV cables can be single-core, dual-core, triple-core, or quad-core, meeting various circuit layout requirements.
4. Rated Voltage: This cable typically has a rated voltage, such as 0.6/1kV, 3.6/6kV, or 6/10kV, depending on the requirements of the power system.
5. Shielding and Jacket: YJHLV cables can have a metallic shield to provide additional electromagnetic interference suppression. The jacket is typically made of polyvinyl chloride (PVC) or polyethylene (PE) to protect the cable from physical damage and environmental factors.
II. Characteristics
1. Excellent Electrical Performance: YJHLV cables offer excellent electrical properties, including low resistance, low inductance, and low capacitance, which help minimize losses during power transmission.
2. Heat Resistance: XLPE-insulated YJHLV cables operate stably in high-temperature environments and are suitable for power transmission and distribution in tropical and high-temperature regions.
3. Corrosion Resistance: Copper-conductor YJHLV cables offer high resistance to corrosion and are suitable for use in humid or corrosive environments.
4. Electromagnetic Interference Resistance: YJHLV cables with metallic shields can reduce electromagnetic interference and ensure circuit stability.
5. Abrasion Resistance: PVC or PE-sheathed versions of YJHLV cables offer a certain degree of abrasion resistance, making them suitable for underground or surface installations.
6. Standards Compliance: YJHLV cables typically comply with International Electrotechnical Commission (IEC) and national standards, ensuring their quality and performance meet relevant requirements.
