Model S (Crossover) Benders for CTC and Straps – Hydraulic & Battery-Powered Versions

bend it – don’t damage it

Model S (Crossover) Benders – Hydraulic & Battery-Powered Versions

The Model S (Crossover) Benders have been specifically designed for precision bending of CTC conductors and copper straps, producing a perfect S-shaped bend without damaging the copper wrapping paper.

Designed to meet the requirements of transformer winding operations, these tools combine precision, reliability and ease of use, ensuring consistent bending results while preserving the integrity of the conductor insulation.

  • H: 1–8 mm
  • L: 50–80 mm

4. S35B – Battery-Powered Bender

The S35B is the battery-powered version of our best-selling S35 model. It offers the same working dimensions as the S35H while providing the flexibility and mobility of cordless operation.

Its adjustable L dimension allows it to accommodate different bending requirements.

The S35B is available in two configurations:

  • Standard
  • Mirrored

Customers must specify their preferred configuration when placing an order.

Working dimensions:

  • A: 5–30 mm
  • B: 15–35 mm
  • H: 1–8 mm
  • L: 50–80 mm

5. S80 – Hydraulic Bender

The S80 is the largest model in the Model S (Crossover) range. It is designed for bending larger copper conductors and straps, providing a solution for applications requiring greater working dimensions.

Working dimensions:

  • A: 8–30 mm
  • B: 25–80 mm
  • H: 1–8 mm
  • L: 65 mm

Model Comparison

All dimensions are expressed in millimetres (mm).

Model Identification

The letters used in the model names indicate the power system or specific design configuration:

  • H – Hydraulic version.

Technical Information

HS Classification

All Model S (Crossover) Benders are classified under the following HS Code:

  • HS Code: 8504.90.90

Hydraulic Benders – Enerpac Hydraulic System

Hydraulic Bender models operate using an Enerpac hydraulic system, consisting of three main components:

Hydraulic Cylinder – Enerpac RC53

  • Model: Enerpac RC53
  • HS Code: 8412.21.80.90
  • Supply: Included with the Hydraulic Bender and in its purchase price.
  • Installation: Mounted directly on the Bender.

Hydraulic Pump – Enerpac PA133

  • Model: Enerpac PA133
  • HS Code: 8413.50.61.90
  • Weight: Approximately 6 kg.
  • Supply: Available for separate purchase.

High-Pressure Hydraulic Hose – Enerpac HC7210

  • Model: Enerpac HC7210
  • HS Code: 3917.31.00.90
  • Weight: Approximately 2 kg.
  • Supply: Available for separate purchase.

Compressed-Air Requirements and Operation

The Enerpac hydraulic pump must be connected to the compressed-air supply available at the customer’s production facility.

The required operating specifications are:

  • Air pressure: 8 bar
  • Air consumption: 340 L/min

Once connected to the compressed-air supply, the Hydraulic Bender is immediately ready for operation.

The operating pedal is integrated directly into the hydraulic pump and connected to the Bender through a high-pressure hydraulic hose. This configuration allows the operator to control the bending process conveniently using the foot pedal.

Maintenance and Hydraulic Oil

Hydraulic Benders are designed to require minimal maintenance under normal operating conditions.

The main routine maintenance requirement is to periodically check the hydraulic oil level in the pump and ensure that it remains within the recommended operating range.

  • Recommended hydraulic oil: ISO VG 46 (ISO 46) hydraulic oil.

Optional Accessory – SIRA FLEX Tool Balancer

To further improve operator comfort and ergonomics, we recommend using a SIRA FLEX tool balancer, selected according to the appropriate maximum load capacity.

Technical specifications:

  • Brand: SIRA
  • Model: FLEX
  • HS Code: 8431.39.90
  • Weight: Approximately 6 kg.
  • Supply: Available for separate purchase.
  • Load capacity: Selected according to the weight of the Bender.

The balancer supports the weight of the Bender, allowing the winding operator to handle the tool more comfortably without having to support its full weight manually throughout the working process.

This accessory is particularly useful during prolonged operations, helping to reduce physical strain and operator fatigue while improving workplace ergonomics.

Battery-Powered Bender – S35B

The S35B is equipped with a professional cordless drive system based on the Bosch Professional PRO GSR 18V-50 Cordless Drill/Driver.

Each Battery Bender is supplied with the following equipment:

  • 1 × Bosch Professional PRO GSR 18V-50 Cordless Drill/Driver
  • 1 × Bosch Professional ProCORE18V 4.0 Ah Li-Ion Battery
  • 1 × Bosch Professional GAL 18V-40 Battery Charger

The S35B is available in two configurations: Standard and Mirrored.

Customers must indicate their preferred configuration when placing an order to ensure the Bender is supplied according to their specific production requirements.

Standard Equipment – Protective Carrying Case

All Hydraulic and Battery-Powered Model S (Crossover) Benders are supplied with a dedicated hard protective case.

The case is designed to ensure safe transportation, handling and storage of the equipment, helping protect the Bender and its components when not in use.
