Standard for 300mm2 XLPE cableÂ
Hongda 300mm2 XLPE cable is manufactured according to the standard of GB12706 or IEC,BS,DIN and ICEA upon request.
Â
Applications for 300mm2 XLPE cableÂ
XLPE cable is suitable for dynamic line transmission and distribution lines of shielding performance requirements more stringent,especially applies to the rated voltage 0.6/1kV and below frequency inverter control system for power supply or connectiing cables.Frequency conversion cable is actually a shield-type power cable,the difference is that ground wires are divided into third part placed in the three main line between core to uniform electric field and improve levels of electromagnetic radiation of cable.Mostly used in high-power inverter power supply and frequency conversion motor connection
Â
Operating characteristics for 300mm2 XLPE cable
1.Rated power-frequency voltage Uo/U of electrical cable : 0.6/1kV
2.Max.permissible continuous operating temperature of electrical cable conductor: 90°C
3.Max.short-circuit temperature of electrical cable conductor shall not exceed 250°C.(5s maximum)
4.The ambient temperature under installation should not below 0°C
5.The bending radius of electrical cable should not less than 15 times of electrical cable diameter.

Three cores
We offer various small type components for FTTH installation such as braching clip, bare fiber protection tubing, ftth drop cable protection tubes and boxes and so on. The branching clip is used to branch fiber cables. And we have many other fiber optic accessories such as thermo tube, fiber optic protective sleeve, fiber optic splice tray and holder for fiber protective sleeves. ftth drop cable protection tubes, also known as optical fiber protection tube, bare fiber protective tube made of low density polyethylene (LDPE) direct extrusion molding, mainly used for optical cable connector box, optical distribution frame, optical fiber segment and junction box bare fiber maintenance exposed peel. Can be used to maintain bare fiber without damage, not easy to damage. Branch off clip is casted by aluminum and coated by high temperature adhesive, molded by EVA and PA hot melt. This product is used for jointing with cables. This divided into two or three branches up to good breaking up.
