托盤(pán)線槽橋架的質(zhì)量要求可從多個(gè)維度進(jìn)行綜合分析，結(jié)合行業(yè)標(biāo)準(zhǔn)及實(shí)際應(yīng)用需求。

　　The quality requirements for tray cable trays can be comprehensively analyzed from multiple dimensions, combined with industry standards and practical application needs.

　　好質(zhì)量橋架應(yīng)表面平整光滑，無(wú)劃痕、凹陷、氣泡或毛刺，焊縫均勻無(wú)漏焊、燒穿等問(wèn)題。涂層需均勻且附著力強(qiáng)，防腐性能關(guān)鍵。例如，鋅鋁鎂涂層厚度220μm,耐鹽霧性能需過(guò)1000小時(shí)。邊角應(yīng)圓滑無(wú)銳角，避免安裝或使用中損傷電纜或人員。常見(jiàn)材質(zhì)包括鍍鋅鋼、鋁合金、鋅鋁鎂等。鍍鋅層厚度需>12.6μm，戶(hù)外環(huán)境建議使用PVDF涂層。托盤(pán)式橋架的U型截面設(shè)計(jì)可提升抗彎剛度，符合標(biāo)準(zhǔn)。底板厚度少2.0mm, 側(cè)板1.5mm以上，確保載荷匹配。焊接部位需無(wú)裂縫/氣孔，動(dòng)志荷載測(cè)試需達(dá)標(biāo)。寬度、高度、厚度等需符合行業(yè)標(biāo)準(zhǔn)，長(zhǎng)度偏差、水平度、垂直度需嚴(yán)格控制。切割、折彎工藝需保證尺寸準(zhǔn)，避免變形。生產(chǎn)過(guò)程中需定期檢驗(yàn)。托盤(pán)式橋架散熱優(yōu)于槽式，適合大電流電纜。槽式橋架防火性能更優(yōu)，可降低火焰蔓延速度70%。托盤(pán)內(nèi)電纜填充率60%,梯架70%，以保證散熱和維護(hù)空間。水平支架間距1.5-3.0m,垂直支架2m。轉(zhuǎn)彎處需用連接配件,接地電阻≤40。腐蝕性環(huán)境需選擇耐腐蝕材質(zhì)。

　　Good quality cable trays should have a smooth and even surface, without scratches, dents, bubbles or burrs, and uniform welds without any issues such as missed welding or burn through. The coating should be uniform and have strong adhesion, and the anti-corrosion performance is crucial. For example, a zinc aluminum magnesium coating with a thickness of 220 μ m requires a salt spray resistance of over 1000 hours. The corners should be smooth without sharp angles to avoid damaging cables or personnel during installation or use. Common materials include galvanized steel, aluminum alloy, zinc aluminum magnesium, etc. The thickness of the galvanized layer should be greater than 12.6 μ m, and it is recommended to use PVDF coating for outdoor environments. The U-shaped section design of the tray type bridge can improve the bending stiffness and meet the standards. The bottom plate thickness should be at least 2.0mm, and the side plate thickness should be at least 1.5mm to ensure load matching. The welding area must be free of cracks/pores, and the dynamic load test must meet the standards. Width, height, thickness, etc. must comply with industry standards, and length deviation, levelness, and verticality must be strictly controlled. The cutting and bending processes must ensure accurate dimensions and avoid deformation. Regular inspections are required during the production process. Tray style cable trays have better heat dissipation than trough style ones and are suitable for high current cables. The groove type bridge has better fire resistance and can reduce the flame spread speed by 70%. The cable filling rate inside the tray is 60%, and the ladder frame is 70% to ensure heat dissipation and maintenance space. The distance between horizontal brackets is 1.5-3.0m, and the distance between vertical brackets is 2m. Connection accessories are required at turning points, and the grounding resistance is ≤ 40. Corrosion resistant materials should be selected for corrosive environments.

　　托盤(pán)線槽橋架的質(zhì)量需綜合評(píng)估外觀、材料、結(jié)構(gòu)、功能及安裝要求，同時(shí)參考具體應(yīng)用場(chǎng)景。建議先選擇符合國(guó)標(biāo)且通過(guò)嚴(yán)格生產(chǎn)工藝控制的產(chǎn)品。

　　The quality of tray trunking cable trays needs to be comprehensively evaluated in terms of appearance, materials, structure, function, and installation requirements, while also referring to specific application scenarios. It is recommended to first choose products that comply with national standards and have undergone strict production process control.
