The core information of 95×4 3 - phase 4 - wire underground aluminum cable and 3×185 + 95mm high - voltage cable is as follows:​ • Specification and Structure: 95×4 is of 4 - core design with a single core of 95mm², suitable for 3 - phase 4 - wire system; 3×185 + 95mm consists of 3 phase lines of 185mm² and 1 neutral line of 95mm², meeting the three - phase balance requirement of high - voltage power transmission. Both are optimized for underground laying, with resistance to soil pressure and moisture - proof characteristics.​ • Material and Performance: The conductor is made of aluminum, which is lightweight and cost - effective, suitable for underground installation of large - section cables. Although the insulation material is not specified, high - voltage cables are usually equipped with high - voltage resistant insulation layers (such as XLPE), which can resist corrosion and mechanical impact in underground environments.​ • Application Scenarios: 95×4 is applicable to medium - and high - voltage underground power distribution, such as underground trunk lines in residential quarters or industrial parks; 3×185 + 95mm high - voltage cables are used for higher - power transmission, such as underground transmission lines from substations to users and underground power supply networks in large industrial plants.​ These cables balance transmission efficiency and adaptability to underground environments. Aluminum conductors and reasonable core configuration make them an economical choice for high - voltage underground power transmission.
