The power energy storage system requires the use of energy storage cables for connection, which mainly consist of three parts: conductor, insulation, and sheath. Energy storage cables are used for connecting batteries between mobile energy storage power stations, energy storage demonstration power stations, wind power storage systems, and connecting batteries to inverters.
In fact, in practical applications, the storage space for energy storage batteries is limited, and energy storage cables are susceptible to high temperature heating, electrolyte leakage and corrosion, as well as external environmental factors such as continuous exposure to sunlight, low temperature, and humidity, which have a significant impact on the safety performance and service life of energy storage cables.
So, what performance characteristics do energy storage cables need to have to cope with harsh environments?
Firstly, high flexibility: The conductor part of the Paige Rui energy storage cable is made of twisted Category 6 conductors, which are thinner than the commonly used National Standard Category 5 conductors in the market. This also means that when the copper core specifications are the same, the conductor has more copper wires and higher flexibility. Therefore, the cable is more prone to bending in the relatively narrow storage space of the energy storage battery.
The insulation layer and sheath layer of the energy storage cable are made of high-performance cross-linked polyolefin. Through “irradiation cross-linking”, the acid and alkali resistance, aging resistance and service life of the energy storage cable are further enhanced.
The insulation and sheath layers of energy storage cables are made of low smoke, halogen-free, and high-efficiency flame-retardant materials, which have good resistance to high and low temperatures. Even in extremely cold environments, it combines safety and stability.
The copper core material of energy storage cables is oxygen free pure copper, which has the characteristics of high purity, high toughness, low resistivity, strong conductivity, and strong safety. It has the ability to withstand high currents and can meet the needs of high-power energy storage systems easily.
The insulation and sheath layers of energy storage cables are made of high insulation and environmentally friendly plastics. Before leaving the factory, they undergo multiple strict performance tests, and their products have good insulation properties, which can avoid harm to the working environment and human health.
