The LS-2 power cords occupy a leading position in the GigaWatt power cable offer. They are the culmination of many years of experience and research on the project of a reference power cable.
The priority in creating the LS-2 project was to obtain an uncompromising product without taking into account any limitations related to its production costs. The LS series is also an excellent testing ground for improving existing and constructing new GigaWatt products.
The GigaWatt LS-2 EVO is the next generation of this reference cable. The main construction assumptions remain the same, while the important change is the use of new conductors.
The main design assumptions remain the same, while the use of new conductors is a significant change. Instead of solid wires, we used s multi strand. One thicker wire has been replaced by seven thinner ones, forming a lead with a total cross section of 1,5mm2.
The design is a 9 x 1.5 mm2 lead, where each lead consist of 7 strands, spun in a tight pitch. The conductors are made of silver plated oxygen-free copper with a purity of 5N, produced according to our specifications. This design increases the active surface area of the wire and makes the cable more flexible.
The whole structure is covered by a sealed copper screen, protecting against EMI and RFI noise.
In the cable construction, great importance was also attached to the reduction of vibrations generated by the electromagnetic field induced around conductors. Working wires are surrounded by a multilayered material, dumping unwanted vibrations. From the outside, the cable is additionally protected by a black, textile jacket made of polyolefin fibre and an antistatic mesh that prevents electrostatic accumulation.
Specially dedicated for LS-2 EVO a new loss-free passive filter of nano-crystal alloys was worked out. It is being assembled in a preciously selected spot in a cable and constitutes additional protection against parasitic noises and oscillations on the cable output
Cable assembly is completely manual. Making one piece of LS-2 EVO, power cord requires hours of specialist work, and all stages of the manufacturing process take place under strict control ensuring the highest quality of product and repeatability of subsequent items.
It is also worth noticing, that the cable is equipped with splendid proprietary plugs, made to our specifications. Their massive construction ensures extraordinary durability and reliability. The casing of the plugs is made of compact aluminium. Their solid connectors are made of compact brass covered with rhodium, which guarantees low impedance and a larger amount of connecting cycles with no parameters loss. Connectors were additionally subject to cryogenic treatment and de-magnetization. All conductors are connected with no use of tin, and plug connections are bolted which minimizes plug impedance and guarantees reliability.
LS-2 EVO is recommended particularly for powering high power consumption appliances, although will successfully power reference audio and video sources too. The cable is also available in a high power version as LS-2HCEVO, being a dedicated power cable for the top GigaWatt PC-4 EVO+ power conditioner.
