First, an overview:

Column isolation skilled hand, hand, hand isolation VSL (VS1) -12KV/ car lightning Pt vehicle measurement hand car, fuse car and landing type transformer hand trolley is the company production for many years products. The products of hand car production is divided into air isolation and composite isolation in the production cost and manufacturing, many companies are using air isolation, so as to save the cost and can achieve the same effect and function, so that the products in the market has a thermal response needs. At the same time, the car can be used in electric power, metallurgy, mine, chemical industry and other departments of power transmission and distribution system for control circuit, is also suitable for frequent operation places.

Two, the use of the environment

A ambient air temperature: upper limit of +40, lower -15;

Altitude: B = 100m (for higher altitude, is rated insulation level increase);

C amplitude: no more than 8 degrees earthquake degree;

The daily average value of relative humidity of D is not more than 95%, and the monthly average value is not more than 90%

E no fire, explosion hazards, serious pollution, chemical corrosion and violent vibration place.
