Raw Material Quality Control

Raw Material Quality Control:

Copper Wire Rod: Oxygen-isina tsvimbo yemhangura tsvimbo, yakapihwa neyakatenderedzwa yakachena yakatsetseka pamusoro, hapana chero maburrs, mutswe, unooneka kukuvara kwemuchina uye oxidation discoloration. Diameter kukanganisa uye Vhoriyamu resistivity pa20 ℃ inogona kugamuchirwa.

Aluminium Rod: L4/L9 Aluminium tsvimbo, yakapihwa nekutenderera kwakachena kwakatsetseka, hapana maburrs, mutswe, tsvina yakakora uye kukuvara kwemagetsi kunoonekwa. Diameter kukanganisa uye Vhoriyamu resistivity pa20 ℃ inogona kugamuchirwa.

XPLE Granule uye PVC (yakajairika kana murazvo-inodzoreredza) YeSheath uye Insulation: Zvakajeka zvinoonekwa zvinopa kunyange ruvara granule isina tsvina. Kusimba kwesimba, kurebesa panguva yekuzorora, uye vhoriyamu resistivity zvese zvinosangana nemazinga.

Armored Tape: Simbi tepi/waya yesimbi, Hukobvu uye mhosho yekupamhama inofanirwa kuve inonzwisisika, inopa yakachena yakatsetseka isina-yakakanganisa nzvimbo.

PYJD/PYJJ/PYJBJ/PSD: Inopa kunyange dema ruvara granule, pasina hupfu yakasara, chimiro sechidimbu chimwe. Kusimba kwesimba uye kureba panguva yekuzorora kunofanirwa kugamuchirwa.
Production Process Quality Control:

Conductor Test: Do visually check and measurement by micrometer, conductor resistance test by lab device.

Insulation uye sheath Test: Kuyera ukobvu nelab mudziyo.

Crosslinking Reaction Test: Lab result by thermal elongation test device.

Filler uye yekurara layer: Do visually test, must be in position evenly with no visible damage.

Screen Test: Visually check and measurement by micrometer, conductor resistance test by lab device.

Armored Tape Test: Visually check and measurement by micrometer, situation evaluation about armored around bedding layer and filler.

Kunze Insulation Layer Test: Spark tester by lab, result must be acceptable.
Chigadzirwa Kuedzwa Kusati Kwatumirwa:

Conductor Test: Diameter kuyerwa ne micrometer, uye conductor kuramba bvunzo nelab mudziyo.

Insulation Test: Iko kukanganisa kwehukobvu pasi pe0.1mm. cross section inooneka inopa yunifomu uye flat cut ine even color. Eccentricity ye insulation inofanira kugamuchirwa.

Armored Tape uye Non-metal layer Muedzo: Ukobvu kuyerwa ne micrometer, Chikanganiso mwero unofanirwa kugamuchirwa

Zvemagetsi Lavoratory Muedzo: 4 maawa voltage test, conductor kuramba bvunzo uye Partial Discharge Test.

Kupisa Lavoratory Muedzo: Thermal elongation test, and test for flame retardancy and smoke.

Printed Mark: Print job must be clean and rub-proof.
