Specifications
high elastic silicone rubber
strong anti-tracking and radiation resistance
27.5kV XLPE cable indoor terminal
27.5kV XLPE cable outdoor terminal
27.5kV XLPE cable middle connector Features
1, reliable insulation: imported high elastic silicone rubber preform, always maintain the right radial pressure on the cable body accessories are installed, linked closely together, not for cable runs respiration and interface breakdown within the interface. Stress control part of the main insulation composite as a whole, to effectively solve the problem of electric cable outer shield the fracture stress concentration, to ensure that the insulation, the safe operation;
2, environmental adaptability: the product has a very strong anti-tracking and radiation resistance, excellent weather resistance, corrosion resistance, anti-foul, anti-aging advantages, suitable for high altitudes, cold areas, wet areas, salt fog areas heavily contaminated areas;
3, the selection of fit: the cold shrink structure, each specification is applicable to a variety of cable diameter;
Easy to install: all products are factory preforms, install and operate, no special training, saving time and effort. The shrink Installation solve cable accessories contraction is not tight or loaded into the phenomenon, reducing the quality accidents caused due to improper operation.

- Q:What is the difference between power supply and distribution
- Power supply and distribution is part of the use of general by the Architectural Design Institute of electrical professional
- Q:What are the general requirements for working on distribution equipment?
- Can be plugged into the elbow cable connector, not load operation.
- Q:Transmission lines are not electrical equipment?
- Transmission lines in the power transmission project belongs to the carrier, belonging to the power cable category, should not be called equipment
- Q:What is the role of transmission system and distribution system in power grid
- Such as water resources are concentrated in the river basin water level drop larger place, fuel resources in coal, oil, gas.
- Q:CHINT group in the transmission and distribution equipment to do it?
- The national grid is not purchasing some equipment of CHINT, CHINT group is now very powerful
- Q:An introduction to the interpretation of flexible AC transmission systems
- synchronous compensator (STATCOM), reactive power distribution is mainly used to improve the system, to adjust voltage and improve the voltage stability of the system;
- Q:What is the transmission line, what is the power distribution equipment
- As the name implies, the transmission is by the power plant or power center regional power grid (sending end), to the load center power grid (by the end) of the transmission of electricity; power distribution is to be distributed by the substation or bus power down.
- Q:What are the distribution network equipment
- suburbs, towns and rural areas, further allocation and supply industry, agriculture, commerce, industry and residents with special needs for electricity secto
- Q:High and low voltage distribution equipment
- Low voltage distribution equipment: low voltage distribution panel, switch cabinet, switch board, lighting box, power box and motor control center.
- Q:Power distribution equipment should be prepared before the blackout?
- after the high and low voltage power failure, the work must be carried out before the first inspection
