All UK terminal block design differentiation evident

UK terminal block is the Phoenix Terminal, UK series combined terminal box screw connection structure, designed to comply with standards such as IEC60947-1, GB 14048, apply pressure without special processing or take over the ends of round copper conductors connection purposes.

 

Along with globalization, we need to design systems sold in the world, so system designers are more and more frequent use of UK terminal block power supply products made in other countries. Due to the nominal value and measurement methods in Europe, so the device below the nominal value in the design used in Europe is the common practice. However, many United States personnel were not familiar with the concept of design, without understanding the differences between the various standards, would have been difficult in the design process.

 

 

Continuous improvement of circuit board technology panel hosted by the UK terminal block can be installed on current rise a lot, the current has exceeded the limit of 110A, far more than the level of previous products, which makes the design process using what kind of power supply in UK terminals to meet the system requirements, the problem becomes more complex. In addition, ways to measure performance parameters are also different in different areas, even for the same product given the nominal parameters also have considerable differences. Therefore, to achieve a long-term reliability and low cost, is very important to understand these differences. Additional outside insulation basic insulation is usually the second layer of protection, the essential difference lies in the buffer zone the location of parts are not the same, basic insulation is usually close to live parts. Set up and test requirements above for additional insulation basic insulation, is to identify basic insulation is usually good enough, needs additional insulation to do the ultimate protection. While the requirements below for additional insulation reinforced insulation, because additional insulation withstand the direct impact than reinforced insulation.

 

In many cases, reinforced insulation equivalent to double insulation. Strengthened insulated also cannot completely equivalent Yu double insulated, UK wiring Terminal its fundamental causes is strengthened insulated of composition, often is single of a layer insulated system, do had insulated system analysis of people are knows, insulated material of performance, with material of compact degrees, thickness, weight, are is closely related to, a had insulated system pass a hole of probability, far above two layer insulated system pass of hole superimposed in together formed a pass hole of probability. The grounds for the explanations of 22.33 provides: in II class structure, the liquid in contact with live parts, not in direct contact with reinforced insulation. General double panel minimum line spacing set for 0.3mm, single panel minimum line spacing set for 0.5mm, welding disc and welding disc, and welding disc and had hole or had hole and had hole, minimum spacing set for 0.5mm, can avoid in welding operation process in the appeared "bridge received" phenomenon, such most business board factory are can is easily meet production requirements, and can put yield control have very high, also achieved reasonable of wiring density and the has a more economic of cost. Minimum line spacing is only suitable for low voltage circuits for signal control circuit and a voltage of 63V, when line voltage is greater than this value will normally be in accordance with the 500V/1mm experience value of line spacing. When you select a device, and another factor often overlooked is the termination technique used by the product.
