ACSS--Aluminum Conductor Steel Supported
ACSS is used for overhead distribution and transmission lines.
It is designed to operate continuously at elevated temperatures up to 250Â°C without loss of strength.Â It sags less than a comparable ACSR under electrical loading; it is self-damping if pre-stretched during installation; and its final sags are not affected by long term creep of aluminum.
The advantages make ACSS especially useful in reconductoring applications requiring increased current with existing tensions and clearances, new line applications where structures can be economized because of reduced conductor sag.
ACSS is a composite concentric-lay stranded conductor. Steel strands form the central core of the conductor with two or more layers of aluminum 1350-O wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the "O" temper (fully annealed or soft) aluminum.
ACSS (Aluminum Conductor Steel Supported) is very similar to ACSR (Aluminum Conductor Steel Reinforced).Â But, as their names imply, ACSS depends primarily on the steel core for support, whereas the ACSR is supported by both the aluminum and steel components.

Oriented Strand Boards or OSBs are engineered wood panels where rectangular wood stands are arranged in cross oriented layers and binded together with resin.
Luli Group Co., Ltd, has the capability and capacity to produce high quality OSB yet with competitive pricing. It is the result from the huge investment into latest cutting edge technology from Germany â€“ the world leader in technology, engineering and innovation. Capitalizing on such advancement, Luli Group OSB R&D team continues to develop and design OSB with wider application, higher usability and marketability without neglecting the importance to be environmental friendly.
Advantages of OSB:
These greener options to Plywood are moisture resistant, have high load capacities and are customizable to different sizes, thickness and shapes.Uses of OSB:
OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction. The most common uses are as sheathing in walls, Flooring, and roof decking. OSB also sees some use in furniture production.
