Ultimate Tensile Strength, As Stable As A Rock - Analysis Of The Core Performance Of High-strength Neutral Blocks
In key fields such as industrial power distribution and new energy, the mechanical strength of neutral blocks directly determines system safety. This high-strength zero wire terminal reconstructs connection reliability with breakthrough technology, becoming the preferred solution for extreme working conditions.
The core material lays the foundation for tensile strength. The terminal is made of high-purity copper with a conductivity of ≥ 98% IACS, which is integrally stamped and formed. Compared with traditional brass material, the tensile strength is increased by 50%. Combined with tin plating process, a dual protective layer is formed, which not only resists oxidation and corrosion, but also enhances mechanical rigidity. The insulation shell is made of UL94 V-0 flame-retardant material, which can maintain structural stability in environments ranging from -40 ℃ to 125 ℃, providing full scenario protection for mechanical performance.
Innovative structure achieves extreme tensile strength. Drawing inspiration from the anchoring principle of "tightening with pulling", the terminal is equipped with an Archimedean spiral wire arrangement anchor claw component, combined with double-layer crimping technology, which increases the wire bonding force by more than 30% and achieves a tensile strength of 50N/mm ². Verified by professional pull-out tests, there is no looseness for 1 minute under 10 times the rated tension, far exceeding industry standards, completely solving the problem of connection failure caused by cable pulling.
The reliability of the entire scene has been tested for a long time. In wind power converters, they can withstand strong vibrations and low-temperature start-up impacts, ensuring continuous and stable neutral line circuits; In the photovoltaic combiner box, the contact resistance is always ≤ 0.5m Ω through salt spray test and temperature rise test. From rail transit train distribution to industrial robot production line, it has passed 12 rigorous verifications such as torque test and mechanical life test, becoming the "invisible cornerstone" of equipment safe operation.
The safety of the small component carrying system is ensured by this zero wire terminal, which redefines the connection standard under extreme tension through a triple breakthrough in material, structure, and testing.
