Wannan samfurin ya dace da yanayin da ke da ruwa ko zafi, zai iya hana ruwa shiga cikin kebul don hana rage aikin wutar lantarki na kebul saboda ruwa.

1. Ruwa juriya halaye

1.1 Radial tsayayya:

A lokacin ajiya, sarrafawa, sanya, gudu, saboda hatsari, ta hanyar aikin inji karfi, sa da kebul kare layers lalacewa, ruwa daga karya wuri a kan radial shugabanci, zuwa kebul shiga ciki, sa'an nan kuma zuwa kebul karshen yaduwa, haifar da kebul lantarki yi raguwa. Hanyar hana ruwa ita ce a ƙarƙashin jaket, tare da layi na aluminum composite band, don tabbatar da cewa ruwa da danshi ba za su iya shiga ba.

1.2 Axial tsayayya ruwa

Ruwa kai tsaye daga karshen kebul a gefen sararin samaniya tsakanin daban-daban tsarin layers, shiga cikin kebul zuwa axial shugabanci, sa kebul lantarki aiki raguwa. Hanyar hana ruwa ita ce a kewaye da wani layer na semiconductor ruwa hana yada a ƙarƙashin karfe kariya layer na kebul, a kan karfe kariya layer, sa'an nan kuma a kewaye da wani layer na non-conductive ruwa hana yada irin yada, kamar cika ruwa hana mahada a tsakanin kebul core sararin samaniya, to, ruwa hana sakamako mafi kyau.
