摘要：<p>The protective resisto consists of cup-shaped metal housing (1) whose bottom carries a concentric threaded bolt (2). The metal resistance strip (3) is wound in a helix whose outer end (4) is welded to the housing, while its inner end (5) is welded to a connecting part having a second threaded bolt (6). The connecting part has a stud (8) for retaining the resistance strip end and an anchoring plate (9) of smaller diameter than the inner diameter of the housing. The resistance strip is embedded in a metal oxide powder (10), filled into the top-open housing and compacted under a pressure in excess of 2000 bar. Then the housing open side is coated by a closing synthetic resin layer (11).</p>
