想問一下，UL 83里面的THHN、THWN、THWN-2、T90 Nylon這四個型號有什么區(qū)別？每個型號分別代表什么意思？<div>
</div><div>還有，在哪里有這些型號的英文解釋？望高手指點(diǎn)迷津，謝謝了！</div>

PRODUCT TYPES

Thermoplastic-insulated wire is rated 600 V and is designated as follows:

TW — Indicates a single conductor having flame-retardant, moisture-resistant thermoplastic insulation. The wire is rated 60°C wet or dry.

THHN — Indicates a single conductor having flame-retardant and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 90°C dry only.

THW — Indicates a single conductor having flame-retardant, moisture- and heat-resistant thermoplastic insulation. The wire is rated 75°C wet or dry.

THW-2 — Same as THW except that the wire is rated 90°C wet or dry.

THHW — Indicates a single conductor having flame-retardant, moisture- and heat-resistant thermoplastic insulation. The wire is rated 90°C dry and 75°C wet.

THWN — Indicates a single conductor having flame-retardant, moisture- and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 75°C wet or dry. THWN wire suitable for exposure to mineral oil and to liquid gasoline and gasoline vapors at ordinary ambient temperature is marked "Gasoline and Oil Resistant I" if suitable for exposure to mineral oil at 60°C, or "Gasoline and Oil Resistant II" if the compound is suitable for exposure to mineral oil at 75°C. Gasoline resistant wire has been tested at 23°C when immersed in gasoline. It is considered inherently resistant to gasoline vapors within the limits of the temperature rating.

THWN-2 — Same as THWN except that the wire is rated 90°C wet or dry.

謝謝樓上了，不過我還想問一下，T90 Nylon和TWN75分別是什么意思？

謝謝樓上了，不過我還想問一下，T90 Nylon和TWN75分別是什么意思？

T90 NYLON額定90C的，TWN75 額定75C 潮濕環(huán)境

那T90 Nylon和THHN有什么區(qū)別？TWN75和THWN也有什么區(qū)別？

工作溫度的區(qū)別

工作溫度的區(qū)別？額，可以具體點(diǎn)嗎？本人UL方面的真的是新手，還望樓上多指教！

你看6樓講得很清楚了

但6樓沒有T90 Nylon和TWN75這兩個型號啊？

又沉了
