As a core equipment supplier for power infrastructure projects in Pakistan and Central Asia, Yueyang Electric Power Technology Co., Ltd. consistently delivers specialized solutions for high-temperature and high-humidity environments. The company's flagship products-including TUV-certified 15kV outdoor drop-out fuses, high-temperature fuses rated for 45°C operations, and HY5WZ-51/134 35kV moisture-resistant zinc oxide arresters-have become designated equipment for multiple power plant projects along the China-Pakistan Economic Corridor (CPEC).
In Pakistan's Sindh and Punjab provinces where summer temperatures routinely exceed 45°C with severe sandstorms, Yueyang Electric's wind-resistant drop-out fuses effectively withstand contaminated conditions. The upgraded sealing technology of its 35kV moisture-resistant arresters has achieved zero puncture incidents for three consecutive years at coastal power stations. Field operational data demonstrates that high-temperature fuses deployed in photovoltaic projects reduce failure rates by 60% compared to conventional products.
The containerized transport process employs multimodal solutions: shock-proof packaging at Yueyang's factory, Yangtze River barge shipping to Shanghai Port, followed by sea freight to Karachi. For urgent orders, land transportation via the Khunjerab Pass reduces delivery cycles to under 30 days. Each shipment incorporates humidity monitoring systems and is accompanied by TUV certificates, certificates of origin, and serialized packing lists. On-site inspections by Sino-Pakistani engineer teams verify sealing integrity and spare parts completeness, followed by power-frequency withstand voltage testing.
During recent substation commissioning, engineers optimized fuse time-delay parameters to accommodate local grid fluctuations. Yueyang's upgraded moisture-resistant arresters enable replacement of 14 units within two hours. Customer evaluation states: "The zero-failure record of moisture-proof arresters in humid-hot environments confirms the technical reliability of Chinese manufacturing."
From desert power plants in Central Asia to coastal substations along the Indian Ocean, Yueyang Electric Power safeguards critical CPEC infrastructure. With the new batch of 35kV moisture-resistant arresters departing via the Khunjerab Pass, this power equipment corridor traversing the Karakoram Mountains continues strengthening regional energy cooperation ties.
