Within an ACB, the arc is interrupted by directing a high-velocity blast of compressed air on to the arc zone. The large-pace air cools and sweeps away the ionized gases, facilitating arc extinction.
Baut atau mur harus dipasang dengan hati-hati dan teliti, pastikan bahwa baut atau mur masuk dengan lurus dan rata. Bila perlu, baut atau mur dapat diputar dengan kunci pas untuk memastikan sudah terpasang dengan kencang dan tepat.
Blow-out failure: failure is characterised from the lateral spalling of concrete from the proximity from the anchor's head. This type of failure takes place for anchors (prevalently cast-in-position) installed in close proximity to the sting from the concrete aspect.
The fundamental theory at the rear of an air blast circuit breaker revolves around the rapid quenching from the arc that sorts when present-day stream is interrupted. Every time a fault happens, the circuit breaker contacts separate, developing an arc because of the ionization of the medium among them.
Pemeriksaan Rutin: Lakukan pemeriksaan rutin pada angkur dan system harness untuk memastikan bahwa tidak ada kerusakan atau keausan. Jika ditemukan kerusakan, segera ganti perangkat tersebut.
Pemilihan Lokasi: Pilih lokasi yang kuat dan stabil untuk memasang angkur. Pastikan bahwa struktur yang digunakan dapat menahan beban yang dihasilkan oleh pekerja.

This type of fastener needs a pre-drilled hole—employing a Tapcon drillbit—and they are then screwed into the outlet using a regular hex or phillips bit.
Setiap angkur memiliki kapasitas beban maksimal yang bisa ditopang. Pilih angkur dengan kapasitas beban yang sesuai atau melebihi kebutuhan proyek Anda untuk memastikan keamanan dan stabilitas struktur.
