　　Full inspection of heat-resistant aluminum alloy wires for power transmission transformers according to the national standard JNRLH/G1A-300/40

　　 Lightweight heat-resistant aluminum alloy stranded wire is widely used in 35KV, 110KV, 220KV, 330KV, 500KV, 750KV, and 1000KV substation projects. The addition of alloy components to the wire improves the high temperature performance of the product. The wire has a large cross-section, increased current carrying capacity, high heat resistance, high conductivity, low loss, reduces electrical energy loss, and increases the safety performance of equipment operation. Installation and maintenance are the same as regular wire installation procedures, without the need for any special tools or fixtures. Installation and maintenance are convenient and cost-effective.

　　 Heat resistant wire refers to appropriately increasing the allowable temperature of the wire, which can increase the stable current carrying capacity of the system in case of accidents, thereby improving the normal transmission capacity of the line. Through research, it has been found that adding (Zr) element appropriately to aluminum can improve its heat resistance, which directly affects and leads to the production of steel core heat-resistant aluminum alloy stranded wires. This wire has technical characteristics such as high temperature resistance and large transmission capacity. However, there are also shortcomings such as increased losses, sag, and high conductor costs during high-temperature operation, which affect its application in long-distance transmission lines.
