Rated current has been raised to 350 A per conductor, allowing a single run to feed travel, hoist and auxiliary drives of heavy-duty cranes without paralleling rails.<\/p><h2>Key specifications<\/h2><ul><li>Rated current: 350 A per pole, up to 6 poles (3P + N + PE + control)<\/li><li>Rated voltage: 690 V AC \/ 1000 V DC<\/li><li>Conductor material: high-conductivity copper with stainless-steel contact surface<\/li><li>Housing: flame-retardant PVC, IP23 protection as standard<\/li><li>Travel speed: up to 200 m\/min with dedicated current collectors<\/li><\/ul><p>Contact surfaces are machined after extrusion and protected by a stainless-steel strip at the collector interface, which limits wear on long crane runways. The housing is co-extruded with the conductor, a process that eliminates the air gaps that usually cause vibration and contact bounce at high travel speeds.<\/p><h2>Built for demanding environments<\/h2><p>The rail is available with a UV-stabilised, high-temperature housing for steel mills, foundries and outdoor port applications. A cast-resin or steel-body version can be supplied where the installation is exposed to molten splash, dust or aggressive humidity.<\/p><blockquote><p>Crane builders increasingly want one electrification run that covers the whole machine, including control and communication lines. The new 350 A multipole rail gives them that without a wider profile.<\/p><\/blockquote><figure><img decoding=\"async\" src=\"https:\/\/tenglinelec.com\/wp-content\/uploads\/2026\/10\/case-busbar-1.jpg\" alt=\"Tenglin Releases 350 A Multipole Conductor Rail for Heavy-Duty Cranes\"><figcaption>Multipole conductor rail installed on a crane runway together with a power busbar system.<\/figcaption><\/figure><p>The 350 A multipole conductor rail is available now.
