WIND

 

Wind energy offers many advantages, which explains why it's one of the fastest-growing energy sources in the world. Research efforts are aimed at addressing the challenges to greater use of wind energy.

 

ADVANTAGES OF WIND POWER:

It's a clean fuel source

Wind energy is a domestic source of energy

It's sustainable - and does not pollute.

Wind power is cost effective

Wind turbines can be built on existing farms or ranches

It creates "green" renewable jobs

 

USAGE OF THE METAL:

Copper alloys plays an important role in renewable energy systems. As copper is the highest rated thermal and electrical conductor among the engineering metals, power systems that utilize copper and copper alloys (brass, bronze) generate and transmit energy with maximum efficiency and with minimum environmental impacts. By using copper instead of other lower electrical energy-efficient metal conductors, less electricity needs to be generated to satisfy a given power demand. In addition, copper is one of most recyclable metals available. Many tons of copper is used in modern wind tubines - for many various applications.

 

Applications:
Metalcenter supplies all types of copper and copper alloys (bronze, brass) in power panels, generator, grounds the tower from lightning strikes, and carries the electrical current. Metalcenter supplies into the following applications within wind:

 

usage of copper on windturbine

 

GROUNDING SYSTEMS

Copper is vital to the electrical grounding system - which The grounding system, at the base of the mast, consists of a thick copper ring conductor bonded to the base or located within a meter of the base. The ring is attached to two diametrically opposed points on the mast base. Copper leads extend outward from the ring and connect to copper or copper-clad grounding electrodes. The grounding rings at all turbines on the wind farm are inter-connected, providing a networked system with an extremely small aggregate resistance. The grounding systems typicaly consists of copper wires and copper bus bars

 

ELECTRICAL CONNECTORS

- customized copper busbars (solid, flexible, braided, laminated)

 

LIGTHNING CONDUCTOR

cables & wires - in copper or alu. Also we supply expanded mesh (Tecu Net and other expanded metal mesh). Customized Copper-Carbon, Bronze, Brass components are also supplied for ligthning conductor systems. CABLES & WIRES - copper wire and alu-wires - for power transmission .

 

GENERATORS

Copper bars / copper profiles and short circuit copper rings. Also flat rectangular copper wires wrapped with Mica tape is offered (acc. to IEC60317-0-2) for induction generators for wind turbines.

 

ELECTRONICS & INVERTERS

- copper bus bars (solid, flexible, braided, laminated)

 

EMERGENCY BATTERIES

- copper flexibles and customized tiined bus bars used for electrical conduction in emergency batteries.

 

TRANSFORMERS

copper rolled products (copper strips) are extensively used in the electrical industry for circuit breakers, switches as well as various electrical components used in the high voltage segment. The carefully deburred or rounded edges are the special finishings of this semi-finished product, which is ideal for use in the assembly of electrical coils inside large transformers.

 

POWEL & CONTROL PANELS

- where Metalcenter supply customized bus bars and Bus Bar kits (assemblies) for mounting in the power panels of the wind turbine. Also standard Cu-bars in fixed lengths are supplied.

 

HEAT EXCHANGERS & COOLING SYSTEMS

for cooling the nacelle or other key components in the wind turbine - Metalcenter supplies copper strips and copper sheets / brass sheets - for proper heat transmission.

 

MOULDS FOR WIND TURBINE BLADES

use copper mesh (fx TECU net) and other metal mesh - for optimal heat transfer for hardening of the composite material.

 

OFFSHORE STRUCTURES

- are exposed for corrosion and fouling despite coatings of the off-shore structures. However, the maintainance and the durability of the coatings are challanged, whereas cost-efficient alternative solutions are tested and supplied. Cu-Ni sheathing (cladding) is protecting agains corrosioon (with need of coating) - and is 100% sustainable and competitive solution - also with excellent anti-fouling solutions.
