Memilih Kabel ADSS? Mulailah dengan Span, Bukan Hitungan Serat.(Paket dan Pengiriman1)

Jika Anda mencari kabel ADSS untuk proyek utilitas, telekomunikasi, atau EPC, jangan mulai dengan berapa banyak serat yang Anda butuhkan. Itu mundur. Mulailah dengan panjang bentang. Kemudian periksa tegangan atau lingkungan listrik. Hanya setelah itu Anda harus menetap pada jumlah serat dan konstruksi kabel.

 

Itulah sebenarnya bagaimana proyek overhead nyata menentukan ADSS. IEEE 1222-2019 memperlakukan ADSS sebagai kabel utilitas overhead, sehingga mencakup persyaratan mekanis, listrik, dan pemasangan bersama-sama - bukan hanya spesifikasi optik.

 

Ambil halaman ADSS-S YRTFiber sebagai contoh. Ini menggambarkan kabel udara jaket tunggal mandiri semua-dielektrik dengan pilihan jaket luar PE atau AT, dari 2 hingga 288 serat. Tetapi ada juga tabel teknis yang menunjukkan ketegangan kerja dan rentang rentang rentang yang berbeda untuk desain yang berbeda. Itu saja memberi tahu Anda: ini bukan hanya tentang "berapa banyak inti yang saya butuhkan?"

 

Versi pendek - pilih dalam urutan ini:

Rentang pertama - itu memutuskan desain mekanik dasar.

 

Tingkat tegangan / lingkungan listrik kedua - memberi tahu Anda apakah Anda memerlukan selubung PE atau selubung AT.

Jumlah serat ketiga - tentu, kapasitas penting, tetapi harus sesuai dengan desain mekanik dan lingkungan, bukan menimpanya.

Mengapa pesanan ini? Karena ADSS bukan hanya pembawa serat. Ini adalah kabel udara mandiri yang harus menangani angin, ketegangan, tekanan pemasangan, dan paparan luar ruangan selama bertahun-tahun. Baik lingkup IEEE dan struktur produk YRTFiber mencerminkan hal itu.

 

Langkah 1: Panjang panci

Span adalah filter pertama Anda. Ini secara langsung mempengaruhi pemuatan dan ketegangan kabel. Dalam tabel ADSS-S YRTFiber, baris desain yang berbeda menunjukkan ketegangan kerja maksimal harian, kekuatan putus, dan nilai rentang - kira-kira dari 100 m hingga 800 m, tergantung pada konfigurasi.

 

Satu hal yang juga ditunjukkan halaman mereka (mungkin tidak sengaja) adalah bahwa Anda tidak boleh mempercayai satu nomor rentang judul. Produk yang sama disebut "kabel udara bentang 150 m" dalam judulnya, FAQ mengatakan "dirancang untuk bentang hingga 150 meter," blok teknis mengatakan "rentang maksimal 100 m," tetapi daftar fitur mengatakan "dapat mencapai lebih dari 1000 m," sedangkan tabel menunjukkan desain hingga 800 m. Apa yang memberi? Sederhana: rentang tergantung pada baris desain yang tepat dan kondisi proyek Anda. Jadi langkah yang aman adalah meminta pemasok untuk mengkonfirmasi desain untuk rute Anda yang sebenarnya, bukan hanya mengikuti kata-kata pemasaran.

 

Intinya: bentang adalah variabel desain, bukan label tetap. Pendek, rute standar? Jaket tunggal yang lebih ringan mungkin berfungsi. Rute yang lebih panjang atau beban yang lebih tinggi? Dapatkan konfirmasi desain khusus bentang sebelum memesan.

 

Langkah 2: Tingkat tegangan atau lingkungan listrik

Setelah Anda mengetahui bentang, lihat lingkungan listrik. Di situlah Anda memilih antara selubung PE dan AT. Halaman ADSS-S YRTFiber mencantumkan keduanya sebagai opsi jaket luar, dengan penguatan benang aramid di dalamnya.

 

Praktik industri (berdasarkan standar seperti YD / T 980-2002, DL / T 788-2016, GB / T 18899-2002) mengatakan: jika potensi ruang di area pemasangan tidak lebih tinggi dari 12 kV, gunakan polietilen hitam (Selubung kelas A). Jika di atas 12 kV, Anda ingin poliolefin tahan pelacakan (selubung kelas B). Dalam bahasa pengadaan biasa: PE untuk lingkungan listrik yang tidak terlalu parah, AT ketika Anda membutuhkan ketahanan pelacakan yang lebih kuat.

 

Banyak pembeli hanya mencari berdasarkan tegangan saluran nominal, tetapi pertanyaan rekayasa yang sebenarnya adalah tegangan listrik yang sebenarnya pada posisi pemasangan. IEEE 1222 bahkan menyertakan lampiran untuk meminimalkan medan listrik menggunakan perhitungan potensial ruang - begitulah intinya untuk desain ADSS.

Jadi dari perspektif pembelian:

 

Telekomunikasi udara standar atau rute utilitas berisiko rendah? Selubung PE mungkin baik-baik saja.

Lingkungan medan listrik yang lebih keras? Pergi dengan AT.
