Busbar bushing

Disclosed herein is an insulating bushing adapted to protect a busbar and having improved waterproof performance. The insulating bushing includes: a first bushing provided with a first bushing passage through which the busbar passes; a second bushing provided with a first bushing-receiving portion receiving an upper portion of the first bushing inserted through a lower portion of the first bushing-receiving portion and a second bushing passage through which the busbar passes; and a cover coupled to an outer surface of the second bushing and provided with a cover passage through which the busbar passes.

Insulating bushing

Provided are an abrasion-detection type conveyor belt and a manufacturing method thereof. A polymer composition ratio of is set to 40-60% of styrene-butadiene rubber (SBR) and 60-40% of natural rubber (NR), and an adhesive strength between a cover rubber layer and an abrasion-detection color layer is set to 13 kN/m (33 kgf/inch). As compared to the existing product, material properties of the abrasion-detection color layer are improved to extend the available life of the abrasion detection type conveyor belt. The abrasion-detection type conveyor belt is cost-effective, simplifies a belt line, and reduces an inspection time.
