Bolehkah paip PE digunakan sebagai tiub elektrik?

2025-08-19

Dalam bidang kejuruteraan saluran paip dan pemasangan elektrik, pemilihan bahan yang betul adalah penting, ia berkaitan secara langsung dengan kualiti kejuruteraan, keselamatan penggunaan dan penyelenggaraan kemudian. Paip PE, sebagai paip plastik biasa, telah digunakan secara meluas dalam bidang bekalan air dan saliran, penghantaran gas dan sebagainya, dan produk paip PE bagi paip AD telah mendapat pengiktirafan pasaran kerana kualitinya yang boleh dipercayai. Walau bagaimanapun, dalam amalan, kadangkala terdapat persoalan: sama ada paip PE boleh digunakan sebagai paip elektrik (iaitu, lengan elektrik, paip untuk melindungi wayar dan kabel)?

Untuk menjawab soalan ini, kita perlu terlebih dahulu menjelaskan ciri dan kegunaan masing-masing paip PE dan paip elektrik. Tiub PE, iaitu paip polietilena, mempunyai kestabilan kimia yang baik, rintangan suhu rendah dan kekuatan mekanikal tertentu, sering digunakan untuk menghantar cecair seperti air dan gas. Tiub elektrik, biasanya merujuk kepada paip khas untuk perlindungan pemasangan wayar dan kabel, mempunyai pelbagai bahan. Tiub elektrik PVC-U, paip KBG (paip keluli tergalvani), paip JDG, dll. tiub elektrik khusus ini akan mempertimbangkan sepenuhnya keperluan khas pemasangan elektrik semasa mereka bentuk.

Dari perspektif keselamatan, tiub PE tidak sesuai digunakan secara langsung sebagai tiub elektrik. Pertama, ia adalah masalah rintangan haba. Wayar akan menjana haba semasa operasi bekalan kuasa, terutamanya apabila beban besar atau litar pintas berlaku, suhu akan meningkat dengan ketara. Walaupun tiub PE mempunyai julat rintangan suhu tertentu, rintangan suhu tinggi jangka panjangnya masih mempunyai jurang berbanding dengan tiub juruelektrik khusus (seperti sesetengah tiub juruelektrik PVC-U mempunyai rintangan api dan haba yang lebih baik, dan tiub juruelektrik logam mempunyai rintangan suhu tinggi). Suhu tinggi yang berterusan boleh menyebabkan tiub PE melembutkan, mengubah bentuk, dan juga mencairkan, sekali gus kehilangan kesan perlindungan pada wayar dalaman, dan mempunyai potensi bahaya keselamatan yang besar.

diikuti oleh prestasi kalis api. Tiub juruelektrik khusus, terutamanya yang digunakan dalam elektrik bangunan, biasanya mempunyai ciri kalis api, yang boleh melambatkan penyebaran api apabila berlaku kebakaran dan mengurangkan penjanaan asap toksik. Tiub PE biasa tidak mempunyai keperluan kalis api khusus. Apabila menghadapi nyalaan terbuka, ia boleh membakar dan melepaskan bahan berbahaya, yang tidak kondusif untuk keselamatan kebakaran. 11727498001 Tambahan pula, tiub juruelektrik khusus juga mempunyai perbezaan dalam kemudahan mekanikal dan pembinaan. Sesetengah tiub juruelektrik (seperti tiub logam atau tiub elektroteknikal PVC-U tugas berat) mempunyai rintangan mampatan dan rintangan hentaman yang lebih tinggi, dan boleh melindungi wayar daripada kerosakan mekanikal luaran dengan lebih baik. Semasa proses rentetan, dinding dalam tiub juruelektrik tujuan khas biasanya lebih licin, atau reka bentuk mempunyai struktur tertentu, yang memudahkan peletakan dan pengepaman wayar, dan mengurangkan haus dan lusuh pada lapisan penebat wayar.

Selain itu, spesifikasi pemasangan elektrik juga mempunyai keperluan yang jelas mengenai perkara ini. Dalam reka bentuk elektrik dan spesifikasi pembinaan yang berkaitan, jenis dan piawaian tiub untuk perlindungan talian elektrik ditetapkan, dengan tujuan untuk memastikan operasi sistem elektrik yang selamat dan boleh dipercayai. Menggunakan tiub yang tidak memenuhi spesifikasi bukan sahaja mungkin tidak dapat lulus penerimaan, tetapi lebih penting, risiko keselamatan terkubur untuk kegunaan masa depan.

Sudah tentu, sesetengah orang mungkin menyalahgunakan paip PE sebagai paip berwayar dalam keadaan tidak formal dan sementara tertentu yang tidak mempunyai keperluan keselamatan elektrik yang tinggi dan keadaan persekitaran yang sangat sederhana, tetapi ini sama sekali bukan amalan yang disyorkan.

Secara ringkasnya, paip dan tiub PE mempunyai niat reka bentuk dan senario aplikasi yang berbeza. Tiub PE ialah pilihan yang ideal untuk penghantaran bendalir, manakala perlindungan wayar dan kabel harus memilih dengan ketat selongsong juruelektrik khusus yang memenuhi piawaian kebangsaan. Sebagai pengeluar paip profesional, paip AD juga menyediakan produk selongsong juruelektrik yang mematuhi spesifikasi pemasangan elektrik untuk memenuhi keperluan kejuruteraan yang berbeza. Untuk memastikan keselamatan penggunaan elektrik, kualiti kejuruteraan dan pematuhan dengan peraturan yang berkaitan, jangan gunakan tiub PE sesuka hati sebagai paip elektrik, dan pilih


juruelektrik yang sesuai mengikut keperluan reka bentuk elektrik tertentu.
