Cables THHW itilize 100% kondiktè kwiv mou ki satisfè ASTM B172 estanda epi ki pa gen okenn aliminyòm, asire ki estab ak serye konduktivite . kondiktè a se yon 30 AWG ultra-Fine milti-strand estrikti Twisted (Klas K), ki gen ekselan fleksibilite ak se patikilyèman { Izolasyon itilize segondè fòs dielèktrik sòti materyèl PVC, ki pa sèlman gen bon fòs mekanik, men tou gen lwil oliv ekselan, chalè, asid, ak rezistans imidite . Rating tanperati a nan câbles thHw se -40 degre f a 221 degre f ({{}
Aplikasyon
THHW cables are widely used in fixed wiring systems in industrial, commercial, and residential areas, and are particularly suitable for complex environments that require resistance to high temperatures, oils, acids, and moisture. Its excellent flexibility makes it very suitable for wire connections in power distribution systems, internal wiring in electrical control cabinets, lighting systems, and power lines for electric equipment. Due to its rated temperature of up to 105℃(in a dry environment), it is also suitable for high-temperature operating equipment such as motors, transformers, and large machinery. In addition, THHW cables are often used in factory automation, production line control systems, and highly corrosive environments such as metallurgy and chemical industry to ensure the long-term and stable operation of electrical sistèm .
Patikilarite
Cables thhn itilize izolasyon termoplastik PVC ak nilon etwi amelyore rezistans mete ak pwoteksyon mekanik; Tanperati a rated ka rive jwenn 90 degre nan anviwònman sèk, ak kèk ka rive jwenn 105 degre; Restriksyon yo itilize yo dwe konsidere plis ak anpil atansyon nan aplikasyon pou ak imidite ki wo .
Cables THHW itilize izolasyon PVC, men yo fèt pou rezistans chalè ak WATERPROOFING . Yo gen pi fò enpèmeyab ak rezistans chimik korozyon epi yo apwopriye pou itilize deyò oswa nan tuya
Sètifikasyon
Cables THHW yo se UL sètifye ak satisfè kondisyon sekirite strik an tèm de estrikti kondiktè, pèfòmans elektrik, fòs izolasyon ak flanm dife . An menm tan an, câbles THHW yo tou CSA (Kanadyen Nòm Asosyasyon) sètifye, Kòd Kanadyen / Kòd Canadyen, epi yo apwopriye pou sa yo. Espesifikasyon aplikasyon an nan Kòd elektrik Nasyonal Etazini (NFPA 70), men tou satisfè kondisyon yo pou tap mete nan yon varyete anviwònman mouye oswa sèk .
