Penerangan Produk
Aerial Bundle Cable : Product Description and Specifications
The Aerial Bundle Cable (ABC) series configures insulated overhead conductors for critical LV and MV distribution. Unlike legacy bare wire, this XLPE-insulated design (utilizing AAAC/1350-H19 aluminum) creates a safety-critical barrier, minimizing maintenance requirements. Application Scope: Ranges from 0.6/1kV service drops/lighting to 33kV primary feeders. Structural Options: Manufactured with either an integrated supporting messenger or self-supporting lay, depending on span engineering requirements.

Aerial Bundle Cable : Benefits and Features
Grid Classification: 11kV / 33kV. (Medium Voltage Network).
Suspension Logic: Galvanized Steel Messenger. Provides the structural tensile core for Self-Supporting spans.
Spatial Geometry: Compact Bundled Assembly. Reduces visual footprint and easement width requirements compared to bare wire.
Field Stress Control: Dual Semi-Conductive Screens. Physically enforces radial field uniformity to eliminate partial discharge risks.
Sheath Chemistry: HDPE. Specified for high ESCR (Environmental Stress Crack Resistance) and aging immunity in outdoor weathering.

Production Processes Of Aerial Bundle Cable
Infrastruktur pembuatan kabel udara mengendalikan sistem automasi digital gelung tertutup, menyepadukan terkandas konduktor, penyemperitan penebat dan sarung akhir ke dalam aliran kerja berterusan. Kestabilan proses bergantung pada tatasusunan sensor terbenam yang menjejaki parameter penyemperitan dalam masa nyata, menghapuskan varians manual. Pengesahan kualiti dikuatkuasakan melalui perkakasan dalam talian tertentu, termasuk tolok diameter laser dwi paksi dan penguji percikan voltan tinggi, manakala makmal fizikal menjalankan analisis tegangan dan pemanjangan yang merosakkan untuk mengesahkan pematuhan piawaian antarabangsa sebelum penghantaran.
Pembungkusan Untuk Penghantaran
Untuk memenuhi pelbagai keperluan pengangkutan, terdapat banyak kaedah pembungkusan yang boleh digunakan.
