1 Standard The products should be manufactured according to standard GB/T12706-2008 and also as per IEC, BS and HD as requested. 2 Application The products should be suitable for buried cables under the moist, abundant groundwater or water tree growth inhibiting and safely operating transmission and distribution lines of rated voltages of 3.6/6～26/35kV 3 Properties TR cables should be insulated by electrical and water tree growth inhibiting TR insulated compound. After 729-day water tree ageing accumulation test according to the requirements for tree retardant performance in HD605. The products prolong the cables' lives and improve safety, and they are the upgrade of XLPE insulated cables. Longitudinal water-proof cables combine water-proof material, inhibiting the growth of water tree in the conductor, satisfying the conductivity of the cable; Radical water-proof cables combine Al-plastic tape and polyolefin sheath and have longitudinal and radical water-blocking properties. Insulated water tree retardant property of the cable is requested during the construction of cities. Major projects of some cities designating definitely using water-proofed and water tree retardant cables. It has a bright    market application outlook.

The manufacturing of OPLC adopts the standard of Q/EPRI 038－2011 “Technical Requirements of OPLC”，and the corresponding technical requirements can meet the standard of the enterprises. 2  Scope of application The rated power frequency voltage of the cable is 0.6/1kV or lower than this level. It is also applicable in optical fiber inserting smart grid and network integrating and so on. 3  Features The OPLC adopts the current LV cable as the main body, and successfully inserts the optical fiber unit in the edge gap of the cable. The most obvious characteristics of the OPLS are as following 4 points: Firstly, OPLC integrates the function of both optical fiber and power cable, which can avoids the repeat wiring, and reduce the cost of construction and network setting up as well. Compared to the conventional installation type, using the OPLC as the solution of smart grid user connecting into the network can save a large amount of metal, pipes, plastic materials and so on, and effectively reduces the cost to getting into the communities and end users. Secondly, the flexibility and extension of OPLC is very large. Use the OPLC coordinating with relative equipments and devices, can realize running various business at the same time in one cable, such as, IPTV, Internet connection, MMTel, speech communication, home smart wattmeter and so on. Thirdly, the mechanical performance of OPLC is also very remarkable, such as shock resistance, pressurization, and environment adapting. And complicated ambient situations have been considered into the initial research and design. The performance of the OPLC in the tension, flattening, and impact test carrying out according to the GB/T7424--E1、E3、E4 are all qualified and better than the basic requirement. Last but not least, since the service time of the OPLC is very long, the compatibility of the working temperature between optical unit and power unit is a very important problem. According to the F1 test per the method in GB/T7424, the optical properties reflected from the experiment are all qualified to the requirement in YD/T629, and the electrical properties are qualified to the standard in GB/T12706.1.
