Power cables are used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, internal power supply of enterprises, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.

Thin film capacitors are used for applications such as smoothing currents in HEV and EV inverters. Panasonic’s electronics division claims that it has a share of over 80% in the market. The company’s products have been used in Toyota’s “Priusâ€, Honda’s “Insight†and Nissan’s “LEAF†(Chinese name: Leaf). . However, the previous supply was a special product designed to meet the requirements of automotive manufacturers. Like this, "The development of general supplies is still the first time" (Matsushita). Many manufacturers use the same products to expand the scale of production, which is easy to reduce costs. Matsushita Electronic Products exhibited at the "3rd EV·HEV Drive System Technology Exhibition and the 4th International Auto Electronic Technology Exhibition" (January 18-20, Tokyo Ariake International Convention & Exhibition Center).
There are two types of developments: "Type 1" has a voltage of 450V and a capacity of 581μF; "Type 2" has a voltage of 450V and a capacity of 1000μF. The former can be used for 30-40kW motor, the latter can be used for about 80kW motor. Type 1 has an outer size of 115 x 164 x 43.1 mm and Type 2 has a size of 64.7 x 275 x 71.6 mm. Both are planning to start mass production in 2012.
Both of these products adjust the size of the terminal configuration in order to be used in combination with Infineon's IGBT modules. Type 1 can use 650V, 400A IGBT module "Hybrid PACK 1," and Type 2 can use 650V, 800A "Hybrid PACK 2." In addition, because Pack1 has been mass-produced since about two years ago, it has been adopted by Hyundai's HEV "Sonata Hybrid".
In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system.
The structure of power cable is relatively simple, which can be divided into conductor, internal and external insulation layer, sheath, armor layer and protective layer. The conductor is mainly made of copper and aluminum, which is used to conduct current. The insulating layer is usually wrapped around the conductor to isolate the conductor and so on. There are various types of power cables. If they are classified according to voltage, they can be divided into low-voltage, medium voltage, high-voltage, ultra-high voltage and ultra-high voltage cables.
Advantages
1. Small land occupation. Generally, it is buried in the soil or laid indoors, in ditches and tunnels. The insulation distance between lines is small, without poles and towers. It occupies less land and basically does not occupy space on the ground.
2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
Panasonic Electronic Devices has developed general-purpose film capacitors for electric vehicles (EVs) and hybrid vehicles (HEVs). It is characterized by "general supplies" that are positioned on a variety of vehicles, rather than products that are used only for specific vehicles. This product is mainly sold for the Chinese market. It will be combined with IGBT modules developed by Infineon Technologies of Germany and sold to Chinese auto manufacturers in a packaged manner.
