Cov kauj ruam installation
Cov cuab yeej: Cable stripper, riam, tu hnyav, grounding hlau.
Tsis xav tau rab phom cua sov (cold shrink technology).
1. Sawb Cable: tshem tawm cov txheej txheem, txheej txheej semiconductor, thiab rwb thaiv tsev rau qhov ntev.
2. Npaj tus neeg xyuas pib: huv tus neeg xyuas pib nrog hnyav; smooth txhua tus ntug.
3. Swb ntawm lub tes tsho: tso lub tsho txias lub tes tsho hla lub cable (kom paub meej qhov kev sib raug zoo ntawm theem).
4. Tshem tawm Core & Shrink: rub cov yas kauv core → lub tes tsho cog lus kom nruj rau hauv lub cable.
5. Grounding: Txuas grounding braid rau cable shield thiab ruaj ntseg.

FAQs
Q: Nws puas tuaj yeem rov siv dua yog tias tsis raug?
A: Tsis yog - thaum lub cores raug tshem tawm, shrinkage yog irreversible.
Q: Yuav ua li cas los xyuas kom meej waterproofing?
A: Txheeb xyuas mastic tag nrho qhwv lub cable; siv cov ntaub nplaum tsis muaj dej yog tias xav tau.
Q: Txee lub neej?
A: 2-3 xyoos yog tias khaws cia hauv cov ntim khoom qub (tsis txhob UV / damp).
Q: Nws kav ntev npaum li cas?
A: 20+ xyoo (nyob ntawm cov khoom thiab ib puag ncig)
