Application Examples Of Terminal Blocks In Harsh Environments

cable lugs row has a wide range of applications and different installation environments, including indoors, rooftops, seaside, deserts... As electrical connection equipment, good terminal products need to adapt to a variety of installation environments and have excellent physical properties.

The Caraja mine in Parasi, northern Brazil, is one of the world's largest iron ore mines, with an estimated reserve of 7.2 billion tons of iron, gold, manganese, bauxite, copper, nickel and other valuable ores. In order to ensure the stability, safety and high productivity of such a large mine, the site needs full process automation. Mining operations rely heavily on a nearly 37-kilometer-long ore automated handling conveyor belt system, which can greatly reduce the use of ore transport vehicles with environmental pollution and high carbon emissions, making production stable and efficient. The conveyor system needs to be equipped with a distributed control system (DCS) along the conveyor belt of the conveyor system, and the signals from various parts of the conveyor are transmitted to the control room through the control cabinet. These DCS control cabinets are the core of such complex control systems.

Suppliers responsible for implementing conveyor distributed control system solutions face the following challenges:

1. Thousands of sensors and field devices use 2-wire, 3-wire, and 4-wire wiring configurations and need to be connected to I/O modules. Any surge in these signals can damage expensive I/O modules, so they need fuse protection. Since these signals run near the power cables on site, they also need to be protected from electromagnetic interference, which is achieved by providing grounding for the shielded wires of these cables;

2. In order to better control multiple belt sections, they need to quickly switch various field devices, which require high-frequency solid-state relays with electrical isolation functions to increase safety;

3.wire lugs needs to be installed in a compact cabinet, which is located in an extremely harsh mining environment with extremely harsh environments of mine dust pollution and mechanical vibration;

Provides solutions with high-performance UKK5 series screws electrical lugs and compact ultra-thin relay terminals to solve the challenges faced by these DCS automation control cabinet manufacturers:

1. UK5-HESI series fuses terminal lugs have integrated grounding functions, which can increase the signal wiring volume by 300% per meter;

2. Ultra-thin relays solve the fast switching and electrical isolation requirements required for digital outputs to control field devices. Compared with traditional modular relays, these ultra-thin relays can save 70% of space on the rail;

3. Due to the use of compact multi-layer fuses copper lugs with integrated grounding function and ultra-thin relay terminals, the size of the entire cabinet is reduced by 30%, saving valuable space in the control room.

High-performance UKK5 series screws Aluminum Cable Lug, multi-layer fuse terminals and ultra-thin relay terminals can play an excellent role in control cabinets with narrow engineering. In fact, they help improve the core electrical stability of the entire ore conveying system, increase ore throughput, shorten operation time, and significantly reduce the impact of operations on the environment.
