Jadual Kandungan

Pilihan antara GYXTC8S, GYTC8S dan gyts bergantung terutamanya pada keperluan kiraan gentian, persekitaran pemasangan, tekanan mekanikal dan kekangan belanjawan - terutamanya kos buruh pemasangan.

1. Pilih GYXTC8S (Rajah Tiub Tengah - 8) apabila:

Kiraan gentian adalah rendah (≤24 teras) - biasanya untuk rangkaian capaian, pengedaran FTTH atau pautan jarak pendek.

Kekuatan mekanikal maksimum diperlukan - kekuatan tegangan 3000 - 4000 N dan rintangan remuk 3000 N / 100mm menjadikannya pilihan paling lasak antara ketiga-tiganya. Sesuai untuk persekitaran yang keras, rentang panjang atau kawasan yang mempunyai beban angin / ais yang berat.

Kelajuan pemasangan dan penjimatan kos adalah keutamaan utama - helai keluli bersepadu mengurangkan masa pemasangan dan tenaga kerja sebanyak kira-kira 30% berbanding reka bentuk bukan "menyokong diri". Satu krew boleh menggunakan 3 - 4 km sehari.

Berat bukan kebimbangan utama - pada ~ 140 - 245 kg / km, ia jauh lebih berat daripada GYTC8S dan GYTS, yang boleh menjejaskan kos penghantaran dan pemuatan tiang.

Terbaik untuk: Tulang belakang FTTH luar bandar, laluan udara iklim yang keras dan projek yang memerlukan ketahanan mekanikal yang tinggi dengan kiraan gentian yang rendah.

2. Pilih GYTC8S (Rajah Terkandas - 8) apabila:

Kiraan gentian berjulat dari 24 hingga 144 teras - reka bentuk tiub longgar yang terkandas menyokong ketumpatan gentian yang lebih tinggi, menjadikannya sesuai untuk rangkaian metropolitan dan pautan pengagregatan.

Keseimbangan antara kapasiti gentian dan kos pemasangan diperlukan - ia mengekalkan kelebihan sokongan diri (utusan bersepadu) untuk penggunaan udara yang pantas, sambil menawarkan lebih banyak teras daripada GYXTC8S.

Prestasi mekanikal sederhana boleh diterima - dengan tegangan 1500 N dan rintangan remuk 1500 N / 100mm, ia mengendalikan keadaan udara standard tetapi kurang teguh daripada GYXTC8S.

Berat ialah faktor kritikal- pada ~ 94 kg / km (rujukan teras 12 "), ia adalah kira-kira 30 - 50% lebih ringan daripada GYXTC8S, mengurangkan kos pengangkutan dan pemuatan tiang.

Terbaik untuk: Rangkaian bandar / metro, laluan udara rentang sederhana dan projek yang memerlukan kiraan teras yang lebih tinggi tanpa mengorbankan kecekapan pemasangan.

3. Pilih GYTS (pita keluli terdampar berperisai) apabila:

Pemasangan bukan udara semata-mata - GYTS tidak mempunyai utusan terbina dalam, jadi ia paling sesuai untuk saluran, saluran atau aplikasi pengebumian terus. Untuk kegunaan udara, ia memerlukan talian penghantar keluli yang berasingan, menambah bahan dan kos buruh.

Bajet sangat ketat pada bahan kabel GYTS mempunyai kos bahan yang lebih rendah daripada reka bentuk angka 8. Walau bagaimanapun, jumlah kos projek mungkin lebih tinggi apabila mengambil kira perkakasan utusan tambahan dan pemasangan yang lebih perlahan (20 - 40% lebih tinggi kos pemasangan daripada jenis rajah 8).

Kapasiti gentian adalah tinggi (sehingga 144 teras) dan perlindungan mekanikal masih diperlukan - perisai pita keluli PSP menyediakan perlindungan tikus dan remuk yang sesuai untuk persekitaran bawah tanah atau saluran.

Berat adalah kekangan - pada ~ 78 - 105 kg / km, ia lebih ringan daripada GYXTC8S tetapi setanding dengan GYTC8S.

Terbaik untuk: Laluan pengebumian "saluran" udara campuran, projek dengan infrastruktur utusan sedia ada, atau apabila buruh pemasangan murah dan kos bahan adalah pemacu utama.

Syor Kejuruteraan Akhir

Jika kiraan gentian ≤24 dan ketahanan mekanikal adalah kritikal GYXTC8S ialah pilihan premium untuk penggunaan udara yang pantas dan boleh dipercayai dalam persekitaran yang mencabar.

Jika kiraan gentian > 24 dan kecekapan pemasangan udara masih penting GYTC8S menawarkan keseimbangan terbaik kapasiti teras, berat dan kos pemasangan.

Jika laluan itu terutamanya saluran / pengebumian, atau jika infrastruktur utusan yang berasingan sudah wujud GYTS menyediakan penyelesaian berperisai yang kos efektif, tetapi jumlah kos projek mungkin melebihi alternatif angka 8 apabila pemasangan udara diperlukan.

Petua penjimatan kos: Untuk projek udara sahaja, pengurangan kos pemasangan 30% bagi reka bentuk angka "8 selalunya melebihi kos bahan kabel yang lebih tinggi sedikit, menjadikan GYXTC8S dan GYTC8S lebih menjimatkan sepanjang kitaran hayat projek penuh.
