德國PTL爬電距離測試量規(guī) IEC爬電距離測試卡 供應進口爬電距離測試量規(guī)
PTL爬電距離量規(guī)用以衡量在死亡狀態(tài)下在電壓不足的操作條件下部件之間,同時在電壓不足的操作條件下可接觸的金屬片和部件之間的爬電距離和間隙距離,
這個操作條件根據(jù)IEC和CEE標準公布的:例如:在安裝材料,開關,插頭,插座和電器的條件下

VDE Specifications
Standard Outfit :
1 gauge block, cross section approx. 1 mm x 1 mm, distances between measuring
faces by agreement from 1 mm to 8 mm with a tolerance of -0.02 mm, with shaft, cross section approx. 2 mm x 1 mm,
and with grip, approx. 12 mm x 40 mm x 1 mm, rounded, with bore and engraving
(distance / mm, e. g. "5,0").
Design : made of spring steel, hardened and browned, measuring faces ground plane
parallel, total length approx. 70 mm, Article No.: L 25.XY
with XY = distance between measuring faces in 1/10 mm. Example: the article no. of the creepage distance gauge having a distance between measuring faces of 3,5 mm is: L 25.35
Assortments :
PTL Creepage Distance Gauges Bunch A
with 8 creepage distance gauges:
1,0 - 1,5 - 2,0 - 2,5 - 3,0 - 4,0 - 6,0 - 8,0 mm,
Article No.: L 25.81
PTL Creepage Distance Gauges Bunch B
with 15 creepage distance gauges: 1,0 to 8,0 mm in steps of 0,5 mm,
Article No.: L 25.84
In some publications, standards and specifications, there are distances to be gauged, which are beyond the distance range chosen for PTL creepage distance gauges. To gauge distances below 1 mm, we recommend to use feeler gauges. PTL creepage distance gauges for other distances: on request
