Bare conductors wayoyi ne ko igiyoyi waɗanda ba a rufe su kuma ana amfani da su don isar da wutar lantarki ko sigina.Akwai nau'ikan madugu marasa tushe da yawa, gami da:
Aluminum Conductor Karfe Karfe (ACSR) - ACSR wani nau'i ne na madugu maras amfani wanda ke da ginshiƙin ƙarfe kewaye da ɗaya ko fiye da yadudduka na waya ta aluminum.Ana amfani da shi a cikin manyan layukan watsa wutar lantarki.
All Aluminum Conductor (AAC) - AAC wani nau'in madubi ne wanda aka yi shi da wayoyi na aluminum kawai.Ya fi ACSR sauƙi kuma ba shi da tsada kuma ana amfani da shi a cikin ƙananan layukan rarraba wutar lantarki.
All Aluminum Alloy Conductor (AAAC) - AAAC wani nau'i ne na madugu maras amfani wanda aka yi shi da wayoyi na aluminum.Yana da ƙarfi mafi girma kuma mafi kyawun juriya na lalata fiye da AAC kuma ana amfani dashi da yawa a cikin watsa sama da layin rarrabawa.
Copper Clad Steel (CCS) - CCS wani nau'i ne na madubin da ba a taɓa gani ba wanda ke da ginshiƙin ƙarfe wanda aka lulluɓe da Layer na tagulla.Ana yawan amfani da shi a aikace-aikacen mitar rediyo (RF).
Copper Conductor - Copper conductors wayoyi ne da aka yi da tagulla zalla.Ana amfani da su a aikace-aikace daban-daban, gami da watsa wutar lantarki, sadarwa, da na'urorin lantarki.
Zaɓin madugu mara tushe ya dogara da takamaiman aikace-aikacen da kayan lantarki da na inji da ake buƙata don aikace-aikacen.
