Product Description of Anti oxidation Long life Neutral Block
As the core component of electrical connections, the oxidation resistance and service life of neutral blocks directly determine the stability and safety of electrical systems, especially in complex scenarios such as outdoor, high humidity, and high corrosion. The characteristics of oxidation resistance and long service life are of utmost importance. The following provides a detailed introduction to the neutral blocks that meet the requirements in terms of material, process, and performance, balancing practicality and professionalism.
The core of antioxidant performance lies in the material and surface treatment process. The terminal conductive core adopts high-purity copper substrate with a conductivity of over 98%. Compared with ordinary brass, it has stronger chemical stability and can effectively reduce the occurrence of oxidation reactions. The surface is treated with silver plating, tin plating, or nickel plating to form a dense protective coating that isolates air, water vapor, and substrate contact, avoiding the formation of poor conductors such as copper oxide and copper green, and fundamentally preventing oxidation corrosion. Even long-term use will not cause problems such as blackening or poor contact.
The extension of lifespan is guaranteed through both material upgrades and structural optimization. The insulating shell is made of flame retardant PA66 or PC engineering plastic, which has excellent aging resistance, high and low temperature resistance, and can withstand a wide temperature environment from -40 ℃ to+105 ℃, so as to avoid embrittlement and cracking in long-term use. At the same time, the flame retardant grade reaches V0, improving the use safety. Internally, a spring or screw clamping structure is used, with stable contact pressure and contact resistance ≤ 0.5m Ω, reducing heat loss during current transmission, delaying component aging, and significantly extending service life.
This type of neutral block is suitable for various scenarios, with a rated withstand voltage of up to 600V and a current coverage of 30A to 350A, which can meet different needs such as industrial control, rural power grid, outdoor lighting, etc. Its protection level can reach IP65 or above, which can resist dust and water vapor erosion. With scientific sealing design, it further enhances its antioxidant capacity. Under normal use scenarios, its service life can reach more than 15 years without frequent replacement, reducing maintenance costs and ensuring long-term stable operation of the electrical system.
