Wires & Cables
This is good news for Kansai Cable (HK) Ltd, an export agent specialising in wires for the telecommunications sector. The firm's Japanese parent started out manufacturing multipair cables in 1963.
"Nowadays, our products include a wide range of 50 ohm and 75 ohm coaxial cables, multicore cables and LAN cables," says General Manager John Tsui.
"We sell mainly on the Chinese mainland and in Hong Kong and Macau, in addition to markets overseas," he adds. "We also provide clients with dedicated and specialised professional assistance, technical support and consultation."
Clients include some high-profile names. "We supplied low-loss cables 8D-SFA for the trunk radio system in the Wynn Casino complex in Macau," says Mr Tsui. "Our products also find application in deluxe apartments and hi-tech commercial buildings, including those in the Hong Kong Cyberport, while our multipair cables are used in the new Ma On Shan link to Hong Kong's Mass Transit Railway system."
A typical product is the low-loss type of cable as used in these intelligent buildings - 50 ohm High Foamed Polyethylene (HPEF) insulated type that features:
The problem of faulty and potentially unsafe cable is an issue with stockists and installation firms alike, and this concern is addressed by stringent quality standards in place at Kansai Cable.
The company's EM (or Eco-friendly Material) 75 ohm coaxial cable and EM series multipair cables feature:
"Equally important is the accuracy and validity of the information provided to clients to describe the performance of a cable," says Mr Tsui. "We are exacting in this area, and when we use terminology such as 'low smoke halogen free' then that is exactly what we provide."
Kansai Cable also supplies armoured cable such as zinc-plated FE-armoured communication cable with solid polyethylene insulation. "Digital signal-carrying LAN cables are in strong demand today," says Mr Tsui, "as are common RGB (polyethylene insulated RGB cable with a lead-free PVC sheath) cables that are in widespread use."
The RGB cables are used mainly with projectors. "The control cables range is supplied either with or without shielding, where the extra braiding minimises any electromagnetic interference (EMI)," Mr Tsui adds.
Naturally, Kansai Cable is RoHS-compliant. "This is a must for all cables leaving our factory," Mr Tsui assures. "We can produce any type of cable according to clients' requirements, but outdoor and marine cables are two highly specialised sectors."
There is also healthy demand for cables for high-speed wireless applications. "Future demand for fourth-generation WiMax, Wi-Fi and WLAN requirements is expected to be significant, and we are set to respond to market needs," assures Mr Tsui. "Similarly, with regard to the cables used with IP security cameras."
A new line is HDTV cables, with an impedance of 75 ohms and four layers of shielding. "Cabling for HDTV digital CCTV purposes is now a hot seller," notes Mr Tsui.
Kansai Cable's R&D department keeps a very close eye on advances in technology and how they affect the needs for various cable qualities and parameters, Mr Tsui "Originating in Japan, where great care is taken with quality control, our cables are priced a bit higher than those from elsewhere," he concedes. "However, there is really no comparison with cables made on the mainland."
Kansai Cable (HK) Ltd certainly appears to be well able to meet the stringent demand for hard-wire solutions.
