1. Inner Width: The horizontal width inside the drag chain, usually referenced by the sum of the outer diameters of cables, pipes, etc., with an additional 10% width space.

2. Inner Height: The vertical height inside the drag chain, typically referenced by the maximum height of cables, pipes, etc., with an additional 10% height space.

3. Bending Radius: The minimum radius required when cables, pipes, etc., inside the drag chain bend. It is usually referenced by the maximum bending radius of the internal components, with an additional 10% space to ensure free movement without tension.

4. Load Capacity: The maximum load weight that the drag chain can withstand, depending on the material and design strength.

5. Operating Speed: The speed of equipment movement considered during the design to ensure effective protection even at high speeds.

6. Abrasion Resistance: The resistance of the drag chain's outer shell to wear, ensuring durability over extended use.

7. Protection Class: The protection level of the drag chain against dust, water, and other environmental factors.

8. Operating Temperature Range: The temperature range within which the drag chain can operate normally.

These parameters can be adjusted based on specific application requirements and equipment specifications to ensure that the drag chain effectively protects internal components and meets environmental demands.
