Raw Material Quality Control

Raw Material Quality Control:

Copper Hlau Qws: Oxygen-dawb tooj liab pas nrig, muab los ntawm puag ncig huv si nto, tsis muaj burrs, tawg, pom kev puas tsuaj thiab oxidation discoloration. Txoj kab uas hla yuam kev thiab Volume resistivity ntawm 20 ℃ tuaj yeem ua tau.

Aluminium Rod: L4 / L9 Aluminium pas nrig, muab los ntawm puag ncig huv si nto, tsis muaj burrs, tawg, greasy av thiab pom kev puas tsuaj. Txoj kab uas hla yuam kev thiab Volume resistivity ntawm 20 ℃ tuaj yeem ua tau.

XPLE Granule thiab PVC (ib txwm los yog nplaim taws-retardant) Rau Sheath thiab Rwb thaiv tsev: Ntshiab pom kev muab cov xim granule uas tsis muaj impurities. Tensile lub zog, elongation ntawm tawg, thiab ntim resistivity tag nrho raws li cov qauv.

Armored daim kab xev: Hlau daim kab xev / hlau xaim, Thickness thiab wideness yuam kev yuav tsum tsim nyog, muab huv si du tsis-hloov nto.

PYJD/PYJJ/PYJBJ/PSD: Muab cov xim dub txawm tias granule, tsis muaj hmoov sab laug, zoo li ib thooj. Tensile lub zog thiab elongation thaum so yuav tsum tau txais.
Kev Tswj Xyuas Txheej Txheem Ntau Lawm:

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

Rwb thaiv tsev thiab sheath Test: Thickness ntsuas los ntawm cov khoom siv lab.

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

Filler thiab txaj txaj: Do visually test, must be in position evenly with no visible damage.

Kev kuaj tshuaj ntsuam: Visually check and measurement by micrometer, conductor resistance test by lab device.

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

Sab Nrauv Txheej Txheej Txheej Txheej Txheem: Spark tester by lab, result must be acceptable.
Khoom kuaj ua ntej xa zaub mov:

Conductor Test: Kev ntsuas txoj kab uas hla los ntawm micrometer, thiab kev ntsuas tus neeg xyuas pib los ntawm lub tshuab kuaj.

Rwb thaiv tsev Test: Thickness yuam kev tsawg dua 0.1mm. cross section visually muab ib qho kev sib xws thiab tiaj tus txiav nrog txawm xim. Eccentricity ntawm rwb thaiv tsev yuav tsum tau txais.

Armored Daim kab xev thiab Non-hlau txheej Test: Thickness ntsuas los ntawm micrometer, yuam kev tus nqi yuav tsum tau txais

Hluav taws xob Lrho menyuam Kuaj: 4 teev voltage test, conductor resistance test thiab Partial Discharge Test.

combustion Lrho menyuam Kuaj: Thermal elongation test, and test for flame retardancy and smoke.

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