UL 758, published by Underwriters Laboratories, is the definitive standard for Appliance Wiring Material (AWM). This comprehensive standard sets out specifications for single and multi-core insulated conductors used within factory and production equipment, including internal wiring for connecting appliances. UL758 is one of the most widely recognized safety standards for electrical wiring in North America and globally.

ESUL 758, publicado por Underwriters Laboratories, es el estándar definitivo para Material de Cableado para Electrodomésticos (AWM). Esta norma establece especificaciones para conductores aislados de uno y múltiples núcleos utilizados dentro de equipos de fábrica y producción.

繁中UL 758 由美國保險商實驗室（Underwriters Laboratories）發布，是電器布線材料（AWM）的權威標準。該標準規定了用於工廠和生產設備內部的單芯和多芯絕緣導體的規格，包括連接電器的內部布線。【說明：UL 是美國最具權威性的安全認證機構之一，UL 認證標誌是產品進入北美市場的重要通行證】

UL758 cables and wires cover an exceptionally broad voltage range from 30V up to 1000kV AC and 3kV DC upwards, encompassing low voltage, medium voltage, and high voltage applications. The conductor sizing follows the American Wire Gauge (AWG) system, ranging from 50AWG to 2000kcmil, covering extremely fine signal wires to heavy-duty power conductors.

ESLos cables y alambres UL758 cubren un rango de voltaje excepcionalmente amplio desde 30V hasta 1000kV AC y 3kV DC en adelante, abarcando aplicaciones de bajo, medio y alto voltaje.

繁中UL758 電纜和電線涵蓋從 30V 到 1000kV AC 以及 3kV DC 以上的超寬電壓範圍，包括低壓、中壓和高壓應用。導體尺寸遵循美國線規（AWG）系統，範圍從 50AWG 到 2000kcmil。【說明：AWG 數字越大表示導體越細，kcmil（千圓密爾）用於表示大截面導體】

Tri-Rated Cable is a premium product that carries simultaneous certification to three major international standards: UL (American), CSA (Canadian), and BS (British). This triple certification makes it ideal for manufacturers who export equipment globally, eliminating the need for multiple cable types to meet different regional requirements.

ESEl Cable Tri-Rated es un producto premium que tiene certificación simultánea según tres normas internacionales principales: UL (Americana), CSA (Canadiense) y BS (Británica).

繁中三重認證電纜（Tri-Rated Cable）是同時符合三大國際標準認證的優質產品：UL（美國）、CSA（加拿大）和 BS（英國）。【說明：Tri-Rated 電纜也稱為「面板線」或「控制面板線」，在機電控制設備中應用廣泛】

UL758 appliance wires can be insulated and sheathed in a wide variety of polymers and thermoset materials. The choice of material determines the cable’s resistance to oils, greases, UV light, moisture, and temperature extremes. Internal wiring for factory equipment may only require insulation – an outer sheath is not mandatory under UL758 for internal use, but is required for external equipment connections.

ESLos cables UL758 pueden ser aislados y revestidos con una amplia variedad de polímeros y materiales termoestables. La elección del material determina la resistencia del cable a aceites, grasas, luz UV, humedad y temperaturas extremas.

繁中UL758 電器電線可以使用多種聚合物和熱固性材料進行絕緣和護套。材料的選擇決定了電纜對油脂、紫外線、濕氣和極端溫度的耐受性。工廠設備的內部布線可能只需要絕緣層——UL758 標準對內部使用不強制要求外護套，但用於外部設備連接時必須有護套。【說明：選擇絕緣材料時需考慮工作環境的化學、熱、機械和電氣要求】

Current ratings are based on a conductor operating temperature of 90°C and an ambient air temperature of 45°C, assuming a single cable isolated in free air. Derating factors must be applied for elevated ambient temperatures or grouped installations.

ESLas clasificaciones de corriente se basan en una temperatura de operación del conductor de 90°C y una temperatura ambiente de 45°C, asumiendo un cable individual aislado en aire libre.

繁中載流量數據基於導體工作溫度90°C和環境空氣溫度45°C，假設單根電纜在自由空氣中隔離敷設。【說明：實際載流量需根據安裝條件進行修正計算】
