Posted by admin on Oct 28, 2024 in Technology | 0 comments

1. Scope

This instruction addresses the particular requirements of electrical installation systems for cranes, lifting equipment, transport, and other similar equipment such as escalators, conveyors, bridge trailers, winches, scaffolds, etc.

2. General Requirements

The entire electrical installation can be deactivated by a manually controlled general pole switch located on the main circuit. This switch must be readily accessible from the ground, located in the same room or enclosure as the electrical

Schema Architecture

External Level

Each external view displays only the data relevant to a specific end-user, hiding unnecessary information. Examples: (External View 1), (External View 2).

Conceptual Level

This level describes the overall structure of the database, typically using a relational model where data is stored in tables (Conceptual Schema).

Internal Level

The internal level details the physical data storage, including indexes used for data retrieval (Internal Schema).

Posted by admin on Oct 27, 2024 in Technology | 0 comments

Air Network Components

The electrical distribution air networks in LV consist of the following components: conductors, insulators, and supports.

Conductor Features

Conductors in these networks are typically made of copper or aluminum alloys with adequate electrical and mechanical properties.

Insulated Conductors: These conductors have a coating that provides resistance to the elements. The voltage is 0.6/1kV, and the minimum cross-section is 16mm² for copper (Cu). They are used in LV air networks, perched
