Khoom txhais
Kraft paper-covered wire is manufactured from electrical round copper or aluminum rods that are extruded or drawn through specific molds, annealed, and then wrapped with two or more layers of insulation paper (including kraft paper, high-density insulation paper, heat-resistant paper, turn-to-turn insulation paper, etc.) over the bare copper (Aluminium) conductor. Nws yog tsim los rau windings hauv roj-immersed transformers thiab cov khoom siv hluav taws xob zoo sib xws. Lub extruded liab qab tooj liab (aluminium) ca hlau ua hauj lwm raws li cov tub ntxhais conductor cov ntaub ntawv rau kraft ntawv-cov hlau.

Rwb thaiv tsev Thickness kam rau ua
Lub nominal rwb thaiv tsev thickness (A-a los yog B-b) ntawm kraft ntawv-cov ntaub ntawv tiaj tiaj yuav tsum ua raws li cov cai hauv qab no los yog txiav txim siab los ntawm kev pom zoo ntawm tus neeg muag khoom thiab cov neeg siv khoom:
- Thickness Tsawg dua los yog sib npaug li 0.5 hli: Qhov siab tsis zoo Tsawg dua lossis sib npaug li 10%
- 0.5 mm < Thickness Tsawg dua los yog sib npaug li 1.25 mm: Tsis zoo kam rau ua Tsawg dua lossis sib npaug li 7.5%
- Thickness > 1.25 mm: Tsis zoo kam rau ua Tsawg dua lossis sib npaug li 5%
Faj seeb: Yog hais tias lub thickness poob ntawm ob qib, qhov kam rau ua raws li qib loj yuav tsum siv.
Bending Performance Requirements
Kraft daim ntawv- npog winding hlau yuav tsum ua tau raws li qhov yuav tsum tau ua hauv qab no:
- Rwb thaiv tsev thickness 0.3-0.8 mm: Wrapping test (mandrel txoj kab uas hla 100 mm), Dav - sab dabtsi yog khoov xeem (mandrel txoj kab uas hla 150 mm)
- Rwb thaiv tsev thickness 1.2–4.25 mm: Wrapping test (mandrel diameter 150 mm), Dav -side dabtsi yog khoov xeem (mandrel txoj kab uas hla 200 mm)
