Revision Of Industry Standards For Busducts

Against the ongoing development of the new-type power system and implementation of the dual-carbon strategy, national standards for domestic low-voltage busducts are undergoing systematic revision and phased rollout. Centered on GB7251.6 and GB/T18859, updated specifications have been successively enforced, reshaping industry access thresholds across energy efficiency, safety protection, eco-friendly raw materials and intelligent accessories, and accelerating industrial consolidation and product upgrading.

Aligned with practical engineering demands, the revised standards introduce stricter core performance benchmarks, including lower allowable temperature rise under rated operating conditions and upgraded requirements for short-circuit withstand capacity, fire resistance duration and IP protection rating. Compulsory EMC testing is newly stipulated to curb substandard products from entering construction projects. Green development stands as a core revision focus: the new codes define full-lifecycle carbon footprint calculation rules for busducts, specify permissible recycled conductor ratios and prioritize halogen-free, recyclable insulating materials, phasing out energy-intensive outdated processes and low-end air-insulated products.

Standardized intelligence and scenario-based specifications mark another highlight. Supplementary clauses cover built-in temperature sensors and remote communication for smart busducts deployed in data centers, new energy plants and outdoor infrastructure, mandating reserved monitoring ports to match smart power distribution trends. It is projected roughly 15% of small-scale manufacturers with sloppy material control and inadequate quality management will exit the market, shifting industry resources toward large-scale manufacturers with independent R&D capabilities.

Keeping pace with updated national codes, our company has upgraded the full lineup of cast-resin and compact busducts in-house via our production base and testing laboratory, covering upgrades of 6063 aluminum alloy conductors, epoxy casting techniques and intelligent monitoring configurations to meet full regulatory compliance. Moving forward, we will continue R&D guided by the latest standards, expand domestic and overseas engineering markets and deliver standardized, high-quality products to drive sound industrial development.
