What is the Fluke TL1550EXT 25 ft Extended Test Lead Set?
The Fluke TL1550EXT Extended Test Lead Set is designed for UK electricians and HV technicians carrying out insulation resistance testing with Fluke 1550B, 1550C and 1555 megohmmeters. With 25 ft (7.6 m) low-leakage leads, it gives you the extra reach needed for large switchrooms, substations and industrial installations while maintaining measurement accuracy at high test voltages.
How does the TL1550EXT improve insulation testing on site?
Low-leakage probes and colour-coded leads help reduce measurement errors during 5 kV insulation testing, while robust alligator clips provide secure connections to conductors and earth points. This makes the TL1550EXT ideal for commissioning, maintenance and fault-finding where distance and safety matter.
