Globec (UK) is the authorised stockist and distributor for the PTC and PTR ranges of coaxial lightning protectors designed and manufactured in the USA by Nextek Inc.

PTC protectors employ gas discharge tube technology to protect electrical / electronic equipment from lightning surges in the range DC to 2.5GHz.

This unique rugged design is weather-proof and blocks transients from both sides of the protector.

PTR protectors are similar to the PTC range but include a screw-cap holder for the protection element to facilitate easy access and replacement for a planned maintenance programme.
