Some kinds of cable

Rubber Cable is constructed with a heavyduty HOFR outer sheath which is heat resisting, oil resisting and flameretardant. It is designed to be used in dry and damp places, in open-built plants, underheavy conditions, in mobile motors, electrical trains, agricultural tools andplants, clear water plants.

Rubber cables vary from the lightweight and for standard application, to more robust and for roles under more duress. These tough yet flexible rubber sheathed cables all conform to CENELEC specifications (European Committee for Electro Technical Standardization). These regulation standard rubber cables are ideal for use in indoor, outdoor, damp or wet conditions. The H05RR-F, for example, is ideal for lightweight hand and workshop tools whilst the H07RN-F is more suitable for increasingly higher levels of stress and heavy duty equipment.

Solar technology will be one of the green energy technology in the future.The solar and photovoltaic applications have an increasingly widespread in China.
With the exception of the rapid development of photovoltaic plant at the government support, private investors are also building palnts actively and plan to invest the solar energy components selling in the global.
Many countires are in the stage of learning.It's no doubt that enterprises need to learn from these experienced countries and companies of the using in solar energy to get the best profits.
The characteristics of photovoltaic cable is determined by its special cable insulation and sheath material. We call it a crosslinked PE. After the Irradiation accelerator, the the molecular structure of the cable material will change and to provide the aspects of the performence. In fact, Mechanical load of the cable can sharp wire on the edge of the roof during the period of installation and maintenance. At the same time, cable must be under pressure, bending, tension, cross tensile load and strong impact. If the cable sheath strength is not enough, the cable insulation layer will be seriously damaged, which will affect the life of the whole cable, or lead to problems such as short circuit, fire and personnel injury risk.

Some power cables for outdoor overhead use may have no overall sheath. Other cables may have a plastic or metal sheath enclosing all the conductors. The materials for the sheath will be selected for resistance to water, oil, sunlight, underground conditions, chemical vapors, impact, or high temperatures. In nuclear industry applications the cable may have special requirements for ionizing radiation resistance. Cable materials may be specified not to produce large amounts of smoke if burned. Cables intended for underground use or direct burial in earth will have heavy plastic or metal, most often lead sheaths, or may require special direct-buried construction. When cables must run where exposed to mechanical impact damage, they may protected with flexible steel tape or wire armor, which may also be covered by a water resistant jacket.
