Information for cable products and company.
Concentric cable and coaxial cable look very similar, which often leads non professionals to confuse them during procurement, or even assume they are different names for the same product. In fact, they are two completely different technical routes: Concentric cable is a power cable, mainly used to transmit electrical power (for example, service entrance cables … Read more
Single-core and multi-core cables are widely used in electrical design and field installation. Many engineers and buyers tend to select cables based only on past experience. This seemingly small decision may lead to insufficient ampacity, unexpected induced voltage, excessive electromagnetic interference, inflated construction budgets, or even failed project acceptance. No single cable works for every … Read more
Many procurement staff, when selecting cables, see Fire-related markings on the label—including LSZH cables, Flame-retardant cables and Fire-resistant cables—and easily assume that they all belong to the fire protection category and can be used interchangeably. Many selection errors on projects stem from this misunderstanding. Ordinary LSZH low smoke zero halogen cable does not inherently have … Read more
On electrical project procurement lists, the debate between copper (Cu) and aluminum (Al) conductors has never stopped. In the past, aluminum cables were linked to a number of safety incidents caused by immature termination technology in earlier years, which left some engineers wary of aluminum cables. Today, with copper prices high, cost pressure is forcing … Read more
H05RR-F is commonly abbreviated as “300/500V rubber cable.” As a light-duty flexible cable compliant with EN 50525-2-21, H05RR-F uses EPR insulation and a standard rubber sheath (EM3). Its primary design purpose is to withstand minor mechanical stress, making it suitable for portable household appliances, office equipment, and light-duty hand-held tools. H05RR-F is not suitable for … Read more
The voltage class of submarine power cable determines its application scenario. Low-voltage submarine cables address short-distance, low-power end-point supply, while medium-voltage submarine cables are what truly handle power transmission between islands and the mainland and between platforms and the shoreline. The voltage range of medium-voltage submarine cables typically runs from 6/10 kV to 18/30 kV … Read more
When designing high-voltage transmission projects, engineers must address two core requirements: line lightning protection and dedicated communication channels between substations. The traditional solution involves installing separate conventional overhead ground wires and standalone communication cables. This method increases tower load, along with extra material, construction and ongoing maintenance costs. With the rapid expansion of smart grids … Read more
If you have worked on rural or suburban power distribution projects, you know the headaches brought by traditional bare overhead lines. Tree branches grow rapidly in spring and summer; contact between branches and power lines easily triggers tripping. Plastic bags and dry branches carried by strong winds may land on lines and cause short-circuit outages. … Read more
For residential service connections, street lighting and low-voltage distribution projects in the UK, Australia, New Zealand and other overseas markets, concentric cable is a widely used cable type. Unlike standard multi-core power cables, it has neutral/earth conductors helically wrapped around the insulated core. From our experience supporting global projects, many procurement teams mix up the … Read more
On October 1, China celebrates National Day, one of the most important public holidays in the country. It marks the founding of the People’s Republic of China in 1949 and is a time for reflection, gratitude, family, and national pride. The holiday also begins the well-known “Golden Week,” when many people across China travel, rest, … Read more
