Neutral Block Industry: Changes And Impacts Of International Standards
Neutral block industry: changes and impacts of international standards
With the acceleration of the global energy structure transformation, the neutral wire terminal, as the core component of the electrical connection system, is undergoing profound adjustments to its international standards, which have a profound impact on the industry's technological upgrading, market access, and competitive landscape.
Core changes in international standards
Security performance enhancement: The AS/NZS CISPR 15:2025 standard, jointly released by Australia and New Zealand in 2025, for the first time includes mandatory control of ultraviolet/infrared radiation equipment, emergency signs, etc., and clarifies RF interference limits. For the neutral wire terminal, the standard requires that if the output voltage of the driving power supply exceeds 60Vdc, the terminal needs to be reinforced with insulation design. At the same time, wireless lamps need to pass Bluetooth/Wi Fi frequency band compliance testing to reduce electromagnetic interference risks.
Material and process upgrade: The EU RoHS 2.0 directive promotes the lead-free process, and by 2024, the proportion of environmentally friendly terminals has exceeded 62%. The neutral block industry needs to use high conductivity copper alloy (98% IACS conductivity) combined with nano coating technology to expand the working temperature range to -55 ℃~180 ℃, while meeting the insulation requirements of silicon rubber with a withstand voltage of 3000V, in order to meet the high voltage platform requirements of new energy vehicles at 800V.
Structural innovation requirements: In response to the traditional terminal breakage problem, the industry has added a tail cable wrapping tube to transfer bending and wear to the wear-resistant insulation layer area. The experiment shows that the optimized terminal has more than 5 times higher bending resistance than traditional products, especially in low and medium wind speed environments, with significant advantages.
Impact on the industry
Technological threshold improvement: Enterprises need to invest research and development resources to meet the material, process, and structural requirements of new standards, and promote the industry's transformation towards high-end and intelligent.
Market access differentiation: The increase in compliance costs puts greater pressure on small and medium-sized enterprises, while top enterprises consolidate their market position through technology integration and economies of scale.
The intensification of global competition: the tightening of international standards has prompted enterprises to accelerate the layout of "safety regulations+EMC+wireless" one-stop certification solutions, in order to break through trade barriers and seize global market share.
