Iintambo zeplastiki ezinobhedu ezinobumba ezigqunywe ngombane ezisisigxina ezibekwe kwimigodi yamalahle Umfanekiso obonakalayo

Iintambo zeplastiki ezinobhedu ezigqunywe ngobhedu ezifakwe kwimigodi yamalahle

Olu hlobo lwentambo lufanelekile ukuba lusetyenziswe kufakelo olusisigxina kwiintambo zothumelo/zokusasazwa kombane olinganisiweyo ongaphantsi kwe-10KV njengendawo esuka kwigumbi eliphakathi lokusasaza ukuya kwigumbi le-electromechanical, i-substation ye-transformer ehambayo, iworkshop yemigodi ebanzi kunye ne-switchgear.Ikhebula linophawu lokungabikho komlilo ophakamileyo.

Intshayelelo yeMveliso

Kuba iintambo zisetyenziswa emigodini yeemeko ezintsonkothileyo kunye nemekobume emdaka, ezele yirhasi kunye nesmut, imbonakalo ebangelwa lula, iintambo zamandla zeplastiki ezigqunywe ngamadangatya azinazinto zikhankanywe kwisahluko sokuqala sale ncwadana, kodwa zikwanazo ipropati ye-high flame retardant.Phakathi kwabo, lowo onommandla omkhulu we-cross-sectional 50mm nangaphezulu kufuneka adlule ekuvavanyeni ukutshiswa kohlobo lwe-A Ukuqokelela i-Electric Wire & cable.Ukuba ingaphantsi kwe-50mm², kufuneka idlule kuvavanyo lokutshiswa kohlobo B lokuqokelela iingcingo zombane kunye nentambo.

Iimbonakalo

Iintambo zeplastiki ezinobhedu ezigqunywe ngobhedu ezifakwe kwimigodi yamalahle

1. Ubushushu obuphezulu bokusebenza

2. Uzinzo oluqinileyo lwenkonzo kunye nokuchasana nomlilo, ukuqinisekisa ngokufanelekileyo ubomi benkonzo yekhebula.

3. Ubungqina bokudubula

4. Idayimitha yangaphandle encinci

5. Amandla aphezulu oomatshini

6. Umthamo omkhulu wangoku wokuthwala

7. Ukumelana ne-corrosion ephezulu

Le mveliso yintambo yokubeka esisigxina kunye nesigxina kunye ne-voltage elinganisiweyo ye-1KV nangaphantsi kwimigodi yamalahle, kwaye ifanelekile ukuhanjiswa kwamandla kwimigodi yamalahle.Ukuqinisekisa ukhuseleko lwezixhobo kunye nokuhanjiswa kwamandla kwindawo enzima

Olu hlobo lwentambo ilungele ukusetyenziswa kufakelo olusisigxina kwiintambo zothumelo/zokusasaza kwi-voltacesess elinganiselweyo kune-10kV njengendawo esuka kwigumbi lokuhambisa eliphakathi ukuya kwigumbi le-electromechanical, i-movab-e transformer substation, iworkshop yemigodi ebanzi kunye ne-switchgear.Intambo inophawu lwe-oigh flame retardancy.
